 CAISApplication Interactive Services provide the means to create links between an application GUI viewer and the packages which are used to manage selection and presentation. The tools AIS defined in order to do this include different sorts of entities: both the selectable viewable objects themselves and the context and attribute managers to define their selection and display. To orient the user as he works in a modeling environment, views and selections must be comprehensible. There must be several different sorts of selectable and viewable object defined. These must also be interactive, that is, connecting graphic representation and the underlying reference geometry. These entities are called Interactive Objects, and are divided into four types:
 CAIS_AngleDimensionAngle dimension. Can be constructed:
 CAIS_AttributeFilterSelects Interactive Objects, which have the desired width or color. The filter questions each Interactive Object in local context to determine whether it has an non-null owner, and if so, whether it has the required color and width attributes. If the object returns true in each case, it is kept. If not, it is rejected. This filter is used only in an open local context. In the Collector viewer, you can only locate Interactive Objects, which answer positively to the filters, which are in position when a local context is open
 CAIS_AxisLocates the x, y and z axes in an Interactive Object. These are used to orient it correctly in presentations from different viewpoints, or to construct a revolved shape, for example, from one of the axes. Conversely, an axis can be created to build a revolved shape and then situated relative to one of the axes of the view
 CAIS_BadEdgeFilterA Class
 CAIS_C0RegularityFilter
 CAIS_Chamf2dDimensionA framework to define display of 2D chamfers. A chamfer is displayed with arrows and text. The text gives the length of the chamfer if it is a symmetrical chamfer, or the angle if it is not
 CAIS_Chamf3dDimensionA framework to define display of 3D chamfers. A chamfer is displayed with arrows and text. The text gives the length of the chamfer if it is a symmetrical chamfer, or the angle if it is not
 CAIS_CircleConstructs circle datums to be used in construction of composite shapes
 CAIS_ColoredDrawerCustomizable properties
 CAIS_ColoredShapePresentation of the shape with customizable sub-shapes properties
 CAIS_ColorScaleClass for drawing a custom color scale
 CAIS_ConcentricRelationA framework to define a constraint by a relation of concentricity between two or more interactive datums. The display of this constraint is also defined. A plane is used to create an axis along which the relation of concentricity can be extended
 CAIS_ConnectedInteractiveCreates an arbitrary located instance of another Interactive Object, which serves as a reference. This allows you to use the Connected Interactive Object without having to recalculate presentation, selection or graphic structure. These are deduced from your reference object. The relation between the connected interactive object and its source is generally one of geometric transformation. AIS_ConnectedInteractive class supports selection mode 0 for any InteractiveObject and all standard modes if its reference based on AIS_Shape. Descendants may redefine ComputeSelection() though. Also ConnectedInteractive will handle HLR if its reference based on AIS_Shape
 CAIS_DiameterDimensionDiameter dimension. Can be constructued:
 CAIS_DimensionAIS_Dimension is a base class for 2D presentations of linear (length, diameter, radius) and angular dimensions
 CAIS_DimensionOwnerThe owner is the entity which makes it possible to link the sensitive primitives and the reference shapes that you want to detect. It stocks the various pieces of information which make it possible to find objects. An owner has a priority which you can modulate, so as to make one entity more selectable than another. You might want to make edges more selectable than faces, for example. In that case, you could attribute sa higher priority to the one compared to the other. An edge, could have priority 5, for example, and a face, priority 4. The default priority is 5
 CAIS_EllipseRadiusDimensionComputes geometry ( basis curve and plane of dimension) for input shape aShape from TopoDS Root class for MinRadiusDimension and MaxRadiusDimension
 CAIS_EqualDistanceRelationA framework to display equivalent distances between shapes and a given plane. The distance is the length of a projection from the shape to the plane. These distances are used to compare shapes by this vector alone
 CAIS_EqualRadiusRelation
 CAIS_ExclusionFilterA framework to reject or to accept only objects of given types and/or signatures. Objects are stored, and the stored objects - along with the flag settings - are used to define the filter. Objects to be filtered are compared with the stored objects added to the filter, and are accepted or rejected according to the exclusion flag setting
 CAIS_FixRelationConstructs and manages a constraint by a fixed relation between two or more interactive datums. This constraint is represented by a wire from a shape - point, vertex, or edge - in the first datum and a corresponding shape in the second. Warning: This relation is not bound with any kind of parametric constraint : it represents the "status" of an parametric object
 CAIS_GlobalStatusStores information about objects in graphic context:
 CAIS_GraphicTool
 CAIS_IdenticRelationConstructs a constraint by a relation of identity between two or more datums figuring in shape Interactive Objects
 CAIS_InteractiveContextThe Interactive Context allows you to manage graphic behavior and selection of Interactive Objects in one or more viewers. Class methods make this highly transparent. It is essential to remember that an Interactive Object which is already known by the Interactive Context must be modified using Context methods. You can only directly call the methods available for an Interactive Object if it has not been loaded into an Interactive Context. You must distinguish two states in the Interactive Context:
 CAIS_InteractiveObjectDefines a class of objects with display and selection services. Entities which are visualized and selected are Interactive Objects. You can make use of classes of standard Interactive Objects for which all necessary methods have already been programmed, or you can implement your own classes of Interactive Objects. Specific attributes of entities such as arrow aspect for dimensions must be loaded in a Drawer. This Drawer is then applied to the Interactive Object in view. There are four types of Interactive Object in AIS: the construction element or Datum, the Relation, which includes both dimensions and constraints, the Object, and finally, when the object is of an unknown type, the None type. Inside these categories, a signature, or index, provides the possibility of additional characterization. By default, the Interactive Object has a None type and a signature of 0. If you want to give a particular type and signature to your interactive object, you must redefine the methods, Signature and Type. Warning In the case of attribute methods, methods for standard attributes are virtual. They must be redefined by the inheriting classes. Setcolor for a point and Setcolor for a plane, for example, do not affect the same attributes in the Drawer
 CAIS_LengthDimensionLength dimension. Can be constructued:
 CAIS_LineConstructs line datums to be used in construction of composite shapes
 CAIS_LocalContextDefines a specific context for selection. It becomes possible to:
 CAIS_LocalStatusStored Info about temporary objects
 CAIS_MaxRadiusDimensionEllipse Max radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset))
 CAIS_MidPointRelationPresentation of equal distance to point myMidPoint
 CAIS_MinRadiusDimension– Ellipse Min radius dimension of a Shape which can be Edge or Face (planar or cylindrical(surface of extrusion or surface of offset))
 CAIS_MultipleConnectedInteractiveDefines an Interactive Object by gathering together several object presentations. This is done through a list of interactive objects. These can also be Connected objects. That way memory-costly calculations of presentation are avoided
 CAIS_OffsetDimensionA framework to display dimensions of offsets. The relation between the offset and the basis shape is indicated. This relation is displayed with arrows and text. The text gives the dsitance between the offset and the basis shape
 CAIS_ParallelRelationA framework to display constraints of parallelism between two or more Interactive Objects. These entities can be faces or edges
 CAIS_PerpendicularRelationA framework to display constraints of perpendicularity between two or more interactive datums. These datums can be edges or faces
 CAIS_PlaneConstructs plane datums to be used in construction of composite shapes
 CAIS_PlaneTrihedronTo construct a selectable 2d axis system in a 3d drawing. This can be placed anywhere in the 3d system, and provides a coordinate system for drawing curves and shapes in a plane. There are 3 selection modes:
 CAIS_PointConstructs point datums to be used in construction of composite shapes. The datum is displayed as the plus marker +
 CAIS_PointCloudInteractive object for set of points. The presentation supports two display modes:
 CAIS_RadiusDimensionRadius dimension. Can be constructued:
 CAIS_RelationOne of the four types of interactive object in AIS,comprising dimensions and constraints. Serves as the abstract class for the seven relation classes as well as the seven dimension classes. The statuses available for relations between shapes are as follows:
 CAIS_RubberBandPresentation for drawing rubber band selection. It supports rectangle and polygonal selection. It is constructed in 2d overlay. Default configaration is built without filling. For rectangle selection use SetRectangle() method. For polygonal selection use AddPoint() and GetPoints() methods
 CAIS_Selection
 CAIS_ShapeA framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes - vertices, edges, faces etc - in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient - both HLR and non-HLR - of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object
 CAIS_SignatureFilterSelects Interactive Objects through their signatures and types. The signature provides an additional characterization of an object's type, and takes the form of an index. The filter questions each Interactive Object in local context to determine whether it has an non-null owner, and if so, whether it has the desired signature. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is only used in an open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning Some signatures have already been used by standard objects delivered in AIS. These include:
 CAIS_SymmetricRelationA framework to display constraints of symmetricity between two or more datum Interactive Objects. A plane serves as the axis of symmetry between the shapes of which the datums are parts
 CAIS_TangentRelationA framework to display tangency constraints between two or more Interactive Objects of the datum type. The datums are normally faces or edges
 CAIS_TextLabelPresentation of the text
 CAIS_TexturedShapeThis class allows to map textures on shapes. Presentations modes AIS_WireFrame (0) and AIS_Shaded (1) behave in the same manner as in AIS_Shape, whilst new modes 2 (bounding box) and 3 (texture mapping) extends it functionality
 CAIS_TriangulationInteractive object that draws data from Poly_Triangulation, optionally with colors associated with each triangulation vertex. For maximum efficiency colors are represented as 32-bit integers instead of classic Quantity_Color values. Interactive selection of triangles and vertices is not yet implemented
 CAIS_TrihedronCreate a selectable trihedron there are 4 modes of selection : mode = 0 to select triedron ,priority = 1 mode = 1 to select its origine ,priority = 5 mode = 2 to select its axis ,priority = 3 mode = 3 to select its planes ,priority = 2 a trihedron has 1 origine,3 axes,3 planes. Warning For the presentation of trihedra, the default unit of length is the millimetre, and the default value for the representation of the axes is 100. If you modify these dimensions, you must temporarily recover the Drawer. From inside it, you take the aspect in which the values for length are stocked. For trihedra, this is Prs3d_Drawer_FirstAxisAspect. You change the values inside this Aspect and recalculate the presentation. If you want to use extended selection modes, different than 0, you should take care of removing of the shapes from the interactive context that has been computed for selection; it might be necessary when you change selection mode. You can use methods Axis, Point, Plane to retrieve the shapes
 CAIS_TypeFilterSelects Interactive Objects through their types. The filter questions each Interactive Object in local context to determine whether it has an non-null owner, and if so, whether it is of the desired type. If the object returns true in each case, it is kept. If not, it is rejected. By default, the interactive object has a None type and a signature of 0. A filter for type specifies a choice of type out of a range at any level enumerated for type or kind. The choice could be for kind of interactive object, of dimension, of unit, or type of axis, plane or attribute. If you want to give a particular type and signature to your Interactive Object, you must redefine two virtual methods: Type and Signature. This filter is used in both Neutral Point and open local contexts. In the Collector viewer, you can only locate Interactive Objects which answer positively to the positioned filters when a local context is open. Warning When you close a local context, all temporary interactive objects are deleted, all selection modes concerning the context are cancelled, and all content filters are emptied

If you want to build the second sort of shell, you must use BRepOffsetAPI_MakeOffsetShape. A shell is made of a series of faces connected by their common edges.

 CBRepExtrema_Poly
 CBRepExtrema_SelfIntersectionTool class for detection of self-sections in the given shape. This class is based on BRepExtrema_OverlapTool and thus uses shape tessellation to detect incorrect mesh fragments (pairs of overlapped triangles belonging to different faces). Thus, a result depends critically on the quality of mesh generator (e.g., BREP mesh is not always a good choice, because it can contain gaps between adjacent face triangulations, which may not share vertices on common edge; thus false overlap can be detected). As a result, this tool can be used for relatively fast approximated test which provides sub-set of potentially overlapped faces
 CBRepExtrema_ShapeProximityTool class for shape proximity detection. For two given shapes and given tolerance (offset from the mesh) the algorithm allows to determine whether or not they are overlapped. The algorithm input consists of any shapes which can be decomposed into individual faces (used as basic shape elements). High performance is achieved through the use of existing triangulation of faces. So poly triangulation (with the desired deflection) should already be built. Note that solution is approximate (and corresponds to the deflection used for triangulation)

 CBRepExtrema_TriangleSetTriangle set corresponding to specific face

Input data: a) DS; b) The kept parts of the tool; If the map of the kept parts of the tool is not filled boolean operation of the given type will be performed; c) Operation required. Steps: a) Fill myShapes, myRemoved maps; b) Rebuild edges and faces; c) Build images of the object; d) Build the result of the operation. Result: Result shape of the operation required
 CBRepFeat_FormProvides general functions to build form features. Form features can be depressions or protrusions and include the following types:
 CBRepFeat_GluerOne of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which - or up to which - matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. Glueing uses wires or edges of a face in the basis shape. These are to become a part of the feature. They are first cut out and then projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion features can be constructed
 CBRepFeat_MakeCylindricalHoleProvides a tool to make cylindrical holes on a shape
 CBRepFeat_MakeDPrismDescribes functions to build draft prism topologies from basis shape surfaces. These can be depressions or protrusions. The semantics of draft prism feature creation is based on the construction of shapes:
 CBRepFeat_MakeLinearFormBuilds a rib or a groove along a developable, planar surface. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be symmetrical - on one side of the contour - or dissymmetrical - on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however, in case of mechanical features. Here they include extrusion:
 CBRepFeat_MakePipeConstructs compound shapes with pipe features. These can be depressions or protrusions. The semantics of pipe feature creation is based on the construction of shapes:
 CBRepFeat_MakePrismDescribes functions to build prism features. These can be depressions or protrusions. The semantics of prism feature creation is based on the construction of shapes:
 CBRepFeat_MakeRevolDescribes functions to build revolved shells from basis shapes
 CBRepFeat_MakeRevolutionFormMakeRevolutionForm Generates a surface of revolution in the feature as it slides along a revolved face in the basis shape. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral - on one side of the contour - or bilateral - on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion:
 CBRepFeat_RibSlotProvides functions to build mechanical features. Mechanical features include ribs - protrusions and grooves (or slots) - depressions along planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral - on one side of the contour - or bilateral - on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion:
 CBRepFeat_SplitShapeOne of the most significant aspects of BRepFeat functionality is the use of local operations as opposed to global ones. In a global operation, you would first construct a form of the type you wanted in your final feature, and then remove matter so that it could fit into your initial basis object. In a local operation, however, you specify the domain of the feature construction with aspects of the shape on which the feature is being created. These semantics are expressed in terms of a member shape of the basis shape from which - or up to which - matter will be added or removed. As a result, local operations make calculations simpler and faster than global operations. In BRepFeat, the semantics of local operations define features constructed from a contour or a part of the basis shape referred to as the tool. In a SplitShape object, wires or edges of a face in the basis shape to be used as a part of the feature are cut out and projected to a plane outside or inside the basis shape. By rebuilding the initial shape incorporating the edges and the faces of the tool, protrusion or depression features can be constructed

 CGccEntThis package provides an implementation of the qualified entities useful to create 2d entities with geometric constraints. The qualifier explains which subfamily of solutions we want to obtain. It uses the following law: the matter/the interior side is at the left of the line, if we go from the beginning to the end. The qualifiers are: Enclosing : the solution(s) must enclose the argument. Enclosed : the solution(s) must be enclosed in the argument. Outside : both the solution(s) and the argument must be outside to each other. Unqualified : the position is undefined, so give all the solutions.

The "first parameter" gives the "start point" of the bounded curve, and the "last parameter" gives the "end point" of the bounded curve. The length of a bounded curve is finite. The Geom2d package provides three concrete classes of bounded curves:

The coordinate system is the local coordinate system of the circle. The orientation (direct or indirect) of the local coordinate system gives an explicit orientation to the circle, determining the direction in which the parameter increases along the circle. The Geom2d_Circle circle is parameterized by an angle: P(U) = O + R*Cos(U)*XDir + R*Sin(U)*YDir where:
 CGeom2d_ConicThe abstract class Conic describes the common behavior of conic curves in 2D space and, in particular, their general characteristics. The Geom2d package provides four specific classes of conics: Geom2d_Circle, Geom2d_Ellipse, Geom2d_Hyperbola and Geom2d_Parabola. A conic is positioned in the plane with a coordinate system (gp_Ax22d object), where the origin is the center of the conic (or the apex in case of a parabola). This coordinate system is the local coordinate system of the conic. It gives the conic an explicit orientation, determining the direction in which the parameter increases along the conic. The "X Axis" of the local coordinate system also defines the origin of the parameter of the conic

 CGeom2d_OffsetCurveThis class implements the basis services for the creation, edition, modification and evaluation of planar offset curve. The offset curve is obtained by offsetting by distance along the normal to a basis curve defined in 2D space. The offset curve in this package can be a self intersecting curve even if the basis curve does not self-intersect. The self intersecting portions are not deleted at the construction time. An offset curve is a curve at constant distance (Offset) from a basis curve and the offset curve takes its parametrization from the basis curve. The Offset curve is in the direction of the normal to the basis curve N. The distance offset may be positive or negative to indicate the preferred side of the curve : . distance offset >0 => the curve is in the direction of N . distance offset >0 => the curve is in the direction of - N On the Offset curve : Value(u) = BasisCurve.Value(U) + (Offset * (T ^ Z)) / ||T ^ Z|| where T is the tangent vector to the basis curve and Z the direction of the normal vector to the plane of the curve, N = T ^ Z defines the offset direction and should not have null length

 CGeom2d_TransformationThe class Transformation allows to create Translation, Rotation, Symmetry, Scaling and complex transformations obtained by combination of the previous elementary transformations. The Transformation class can also be used to construct complex transformations by combining these elementary transformations. However, these transformations can never change the type of an object. For example, the projection transformation can change a circle into an ellipse, and therefore change the real type of the object. Such a transformation is forbidden in this environment and cannot be a Geom2d_Transformation. The transformation can be represented as follow :

Solutions consist of pairs of points, and an extremum is considered to be a segment joining the two points of a solution. An ExtremaCurveCurve object provides a framework for:

The curve will than be only C1 The curve is defined by a table of points through which it passes, and if required by a parallel table of reals which gives the value of the parameter of each point through which the resulting BSpline curve passes, and by vectors tangential to these points. An Interpolate object provides a framework for: defining the constraints of the BSpline curve,

 CGeom2dConvert_BSplineCurveKnotSplittingAn algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree - Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot.

The key characteristic of these surfaces is that they are parameterized. Geom_Surface demonstrates:
 CGeom_SurfaceOfLinearExtrusionDescribes a surface of linear extrusion ("extruded surface"), e.g. a generalized cylinder. Such a surface is obtained by sweeping a curve (called the "extruded curve" or "basis") in a given direction (referred to as the "direction of extrusion" and defined by a unit vector). The u parameter is along the extruded curve. The v parameter is along the direction of extrusion. The parameter range for the u parameter is defined by the reference curve. The parameter range for the v parameter is ] - infinity, + infinity [. The position of the curve gives the origin of the v parameter. The surface is "CN" in the v parametric direction. The form of a surface of linear extrusion is generally a ruled surface (GeomAbs_RuledForm). It can be:
 CGeom_SurfaceOfRevolutionDescribes a surface of revolution (revolved surface). Such a surface is obtained by rotating a curve (called the "meridian") through a complete revolution about an axis (referred to as the "axis of revolution"). The curve and the axis must be in the same plane (the "reference plane" of the surface). Rotation around the axis of revolution in the trigonometric sense defines the u parametric direction. So the u parameter is an angle, and its origin is given by the position of the meridian on the surface. The parametric range for the u parameter is: [ 0, 2.*Pi ] The v parameter is that of the meridian. Note: A surface of revolution is built from a copy of the original meridian. As a result the original meridian is not modified when the surface is modified. The form of a surface of revolution is typically a general revolution surface (GeomAbs_RevolutionForm). It can be:

The parametrization range for the parameter V is ]-infinite,+infinite[ The position of the curve gives the origin for the parameter V. The continuity of the surface is CN in the V direction
 CGeomAdaptor_SurfaceOfRevolutionThis class defines a complete surface of revolution. The surface is obtained by rotating a curve a complete revolution about an axis. The curve and the axis must be in the same plane. If the curve and the axis are not in the same plane it is always possible to be in the previous case after a cylindrical projection of the curve in a referenced plane. For a complete surface of revolution the parametric range is 0 <= U <= 2*PI. – The parametric range for V is defined with the revolved curve. The origin of the U parametrization is given by the position of the revolved curve (reference). The direction of the revolution axis defines the positive sense of rotation (trigonometric sense) corresponding to the increasing of the parametric value U. The derivatives are always defined for the u direction. For the v direction the definition of the derivatives depends on the degree of continuity of the referenced curve

 CGeomConvert_BSplineCurveKnotSplittingAn algorithm to determine points at which a BSpline curve should be split in order to obtain arcs of the same continuity. If you require curves with a minimum continuity for your computation, it is useful to know the points between which an arc has a continuity of a given order. The continuity order is given at the construction time. For a BSpline curve, the discontinuities are localized at the knot values. Between two knot values the BSpline is infinitely and continuously differentiable. At a given knot, the continuity is equal to: Degree - Mult, where Degree is the degree of the BSpline curve and Mult is the multiplicity of the knot. It is possible to compute the arcs which correspond to this splitting using the global function SplitBSplineCurve provided by the package GeomConvert. A BSplineCurveKnotSplitting object provides a framework for:

 CGeomConvert_BSplineSurfaceKnotSplittingAn algorithm to determine isoparametric curves along which a BSpline surface should be split in order to obtain patches of the same continuity. The continuity order is given at the construction time. It is possible to compute the surface patches corresponding to the splitting with the method of package SplitBSplineSurface. For a B-spline surface the discontinuities are localised at the knot values. Between two knots values the B-spline is infinitely continuously differentiable. For each parametric direction at a knot of range index the continuity in this direction is equal to : Degree - Mult (Index) where Degree is the degree of the basis B-spline functions and Mult the multiplicity of the knot of range Index in the given direction. If for your computation you need to have B-spline surface with a minima of continuity it can be interesting to know between which knot values, a B-spline patch, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the surface, to obtain patches with a constant continuity given at the construction time. If you just want to compute the local derivatives on the surface you don't need to create the BSpline patches, you can use the functions LocalD1, LocalD2, LocalD3, LocalDN of the class BSplineSurface from package Geom

 CGProp_PGPropsA framework for computing the global properties of a set of points. A point mass is attached to each point. The global mass of the system is the sum of each individual mass. By default, the point mass is equal to 1 and the mass of a system composed of N points is equal to N. Warning A framework of this sort provides functions to handle sets of points easily. But, like any GProp_GProps object, by using the Add function, it can theoretically bring together the computed global properties and those of a system more complex than a set of points . The mass of each point and the density of each component of the composed system must be coherent. Note that this coherence cannot be checked.

This sort of presentation object is created, filled and returned by the function PrincipalProperties for any GProp_GProps object, and can be queried to access the result. Note: The system whose principal properties of inertia are returned by this framework is referred to as the current system. The current system, however, is retained neither by this presentation framework nor by the GProp_GProps object which activates it

 CHLRAlgoIn order to have the precision required in industrial design, drawings need to offer the possibility of removing lines, which are hidden in a given projection. To do this, the Hidden Line Removal component provides two algorithms: HLRBRep_Algo and HLRBRep_PolyAlgo. These algorithms remove or indicate lines hidden by surfaces. For a given projection, they calculate a set of lines characteristic of the object being represented. They are also used in conjunction with extraction utilities, which reconstruct a new, simplified shape from a selection of calculation results. This new shape is made up of edges, which represent the lines of the visualized shape in a plane. This plane is the projection plane. HLRBRep_Algo takes into account the shape itself. HLRBRep_PolyAlgo works with a polyhedral simplification of the shape. When you use HLRBRep_Algo, you obtain an exact result, whereas, when you use HLRBRep_PolyAlgo, you reduce computation time but obtain polygonal segments

 CIFSelectGives tools to manage Selecting a group of Entities processed by an Interface, for instance to divide up an original Model (from a File) to several smaller ones They use description of an Interface Model as a graph
 CIFSelect_ActAct gives a simple way to define and add functions to be ran from a SessionPilot, as follows :
 CIFSelect_ActivatorDefines the general frame for working with a SessionPilot. Each Activator treats a set of Commands. Commands are given as alphanumeric strings. They can be of two main forms :
 CIFSelect_AppliedModifiersThis class allows to memorize and access to the modifiers which are to be applied to a file. To each modifier, is bound a list of integers (optionnal) : if this list is absent, the modifier applies to all the file. Else, it applies to the entities designated by these numbers in the produced file
 CIFSelect_BasicDumperBasicDumper takes into account, for SessionFile, all the classes defined in the package IFSelect : Selections, Dispatches (there is no Modifier)
 CIFSelect_CheckCounterA CheckCounter allows to see a CheckList (i.e. CheckIterator) not per entity, its messages, but per message, the entities attached (count and list). Because many messages can be repeated if they are due to systematic errors
 CIFSelect_ContextModifThis class gathers various informations used by Model Modifiers apart from the target model itself, and the CopyTool which must be passed directly
 CIFSelect_ContextWriteThis class gathers various informations used by File Modifiers apart from the writer object, which is specific of the norm and of the physical format
 CIFSelect_DispatchThis class allows to describe how a set of Entities has to be dispatched into resulting Packets : a Packet is a sub-set of the initial set of entities
 CIFSelect_DispGlobalA DispGlobal gathers all the input Entities into only one global Packet
 CIFSelect_DispPerCountA DispPerCount gathers all the input Entities into one or several Packets, each containing a defined count of Entity This count is a Parameter of the DispPerCount, given as an IntParam, thus allowing external control of its Value
 CIFSelect_DispPerFilesA DispPerFiles produces a determined count of Packets from the input Entities. It divides, as equally as possible, the input list into a count of files. This count is the parameter of the DispPerFiles. If the input list has less than this count, of course there will be one packet per input entity. This count is a Parameter of the DispPerFiles, given as an IntParam, thus allowing external control of its Value
 CIFSelect_DispPerOneA DispPerOne gathers all the input Entities into as many Packets as there Root Entities from the Final Selection, that is, one Packet per Entity
 CIFSelect_DispPerSignatureA DispPerSignature sorts input Entities according to a Signature : it works with a SignCounter to do this
 CIFSelect_EditFormAn EditForm is the way to apply an Editor on an Entity or on the Model It gives read-only or read-write access, with or without undo
 CIFSelect_EditorAn Editor defines a set of values and a way to edit them, on an entity or on the model (e.g. on its header)
 CIFSelect_FunctionsFunctions gives access to all the actions which can be commanded with the resources provided by IFSelect : especially WorkSession and various types of Selections and Dispatches
 CIFSelect_GeneralModifierThis class gives a frame for Actions which modify the effect of a Dispatch, i.e. : By Selections and Dispatches, an original Model can be splitted into one or more "target" Models : these Models contain Entities copied from the original one (that is, a part of it). Basically, these dispatched Entities are copied as identical to their original counterparts. Also the copied Models reproduce the Header of the original one
 CIFSelect_GraphCounterA GraphCounter computes values to be sorted with the help of a Graph. I.E. not from a Signature
 CIFSelect_IntParamThis class simply allows to access an Integer value through a Handle, as a String can be (by using HString). Hence, this value can be accessed : read and modified, without passing through the specific object which detains it. Thus, parameters of a Selection or a Dispatch (according its type) can be controlled directly from the ShareOut which contains them
 CIFSelect_ListEditorA ListEditor is an auxiliary operator for Editor/EditForm I.E. it works on parameter values expressed as strings
 CIFSelect_ModelCopierThis class performs the Copy operations involved by the description of a ShareOut (evaluated by a ShareOutResult) plus, if there are, the Modifications on the results, with the help of Modifiers. Each Modifier can work on one or more resulting packets, accoding its criteria : it operates on a Model once copied and filled with the content of the packet
 CIFSelect_ModifEditFormThis modifier applies an EditForm on the entities selected
 CIFSelect_ModifierThis class gives a frame for Actions which can work globally on a File once completely defined (i.e. afterwards)
 CIFSelect_ModifReorderThis modifier reorders a whole model from its roots, i.e. according to <rootlast> status, it considers each of its roots, then it orders all its shared entities at any level, the result begins by the lower level entities ... ends by the roots
 CIFSelect_PacketListThis class gives a simple way to return then consult a list of packets, determined from the content of a Model, by various criteria
 CIFSelect_ParamEditorA ParamEditor gives access for edition to a list of TypedValue (i.e. of Static too) Its definition is made of the TypedValue to edit themselves, and can add some constants, which can then be displayed but not changed (for instance, system name, processor version ...)
 CIFSelect_SelectAnyListA SelectAnyList kind Selection selects a List of an Entity, as well as this Entity contains some. A List contains sub-entities as one per Item, or several (for instance if an Entity binds couples of sub-entities, each item is one of these couples). Remark that only Entities are taken into account (neither Reals, nor Strings, etc...)
 CIFSelect_SelectAnyTypeA SelectAnyType sorts the Entities of which the Type is Kind of a given Type : this Type for Match is specific of each class of SelectAnyType
 CIFSelect_SelectBaseSelectBase works directly from an InterfaceModel : it is the first base for other Selections
 CIFSelect_SelectCombineA SelectCombine type Selection defines algebraic operations between results of several Selections It is a deferred class : sub-classes will have to define precise what operator is to be applied
 CIFSelect_SelectControlA SelectControl kind Selection works with two input Selections in a dissymmetric way : the Main Input which gives an input list of Entities, to be processed, and the Second Input which gives another list, to be used to filter the main input
 CIFSelect_SelectDeductA SelectDeduct determines a list of Entities from an Input Selection, by a computation : Output list is not obliged to be a sub-list of Input list (for more specific, see SelectExtract for filtered sub-lists, and SelectExplore for recurcive exploration)
 CIFSelect_SelectDiffA SelectDiff keeps the entities from a Selection, the Main Input, which are not listed by the Second Input
 CIFSelect_SelectEntityNumberA SelectEntityNumber gets in an InterfaceModel (through a Graph), the Entity which has a specified Number (its rank of adding into the Model) : there can be zero (if none) or one. The Number is not directly defined as an Integer, but as a Parameter, which can be externally controled
 CIFSelect_SelectErrorEntitiesA SelectErrorEntities sorts the Entities which are qualified as "Error" (their Type has not been recognized) during reading a File. This does not concern Entities which are syntactically correct, but with incorrect data (for integrity constraints)
 CIFSelect_SelectExploreA SelectExplore determines from an input list of Entities, a list obtained by a way of exploration. This implies the possibility of recursive exploration : the output list is itself reused as input, etc... Examples : Shared Entities, can be considered at one level (immediate shared) or more, or max level
 CIFSelect_SelectExtractA SelectExtract determines a list of Entities from an Input Selection, as a sub-list of the Input Result It works by applying a sort criterium on each Entity of the Input. This criterium can be applied Direct to Pick Items (default case) or Reverse to Remove Item
 CIFSelect_SelectFlagA SelectFlag queries a flag noted in the bitmap of the Graph. The Flag is designated by its Name. Flag Names are defined by Work Session and, as necessary, other functional objects
 CIFSelect_SelectIncorrectEntitiesA SelectIncorrectEntities sorts the Entities which have been noted as Incorrect in the Graph of the Session (flag "Incorrect") It can find a result only if ComputeCheck has formerly been called on the WorkSession. Else, its result will be empty
 CIFSelect_SelectInListA SelectInList kind Selection selects a List of an Entity, which is composed of single Entities To know the list on which to work, SelectInList has two deferred methods : NbItems (inherited from SelectAnyList) and ListedEntity (which gives an item as an Entity) which must be defined to get a List in an Entity of the required Type (and consider that list is empty if Entity has not required Type)
 CIFSelect_SelectIntersectionA SelectIntersection filters the Entities issued from several other Selections as Intersection of results : "AND" operator
 CIFSelect_SelectionA Selection allows to define a set of Interface Entities. Entities to be put on an output file should be identified in a way as independant from such or such execution as possible. This permits to handle comprehensive criteria, and to replay them when a new variant of an input file has to be processed
 CIFSelect_SelectionIteratorDefines an Iterator on a list of Selections
 CIFSelect_SelectModelEntitiesA SelectModelEntities gets all the Entities of an InterfaceModel
 CIFSelect_SelectModelRootsA SelectModelRoots gets all the Root Entities of an InterfaceModel. Remember that a "Root Entity" is defined as having no Sharing Entity (if there is a Loop between Entities, none of them can be a "Root")
 CIFSelect_SelectPointedThis type of Selection is intended to describe a direct selection without an explicit criterium, for instance the result of picking viewed entities on a graphic screen
 CIFSelect_SelectRangeA SelectRange keeps or rejects a sub-set of the input set, that is the Entities of which rank in the iteration list is in a given range (for instance form 2nd to 6th, etc...)
 CIFSelect_SelectRootCompsA SelectRootComps sorts the Entities which are part of Strong Componants, local roots of a set of Entities : they can be Single Componants (containing one Entity) or Cycles This class gives a more secure result than SelectRoots (which considers only Single Componants) but is longer to work : it can be used when there can be or there are cycles in a Model For each cycle, one Entity is given arbitrarily Reject works as for SelectRoots : Strong Componants defined in the input list which are not local roots are given
 CIFSelect_SelectRootsA SelectRoots sorts the Entities which are local roots of a set of Entities (not shared by other Entities inside this set, even if they are shared by other Entities outside it)
 CIFSelect_SelectSentThis class returns entities according sending to a file Once a model has been loaded, further sendings are recorded as status in the graph (for each value, a count of sendings)
 CIFSelect_SelectSharedA SelectShared selects Entities which are directly Shared by the Entities of the Input list

 CIFSelect_SelectSignatureA SelectSignature sorts the Entities on a Signature Matching. The signature to match is given at creation time. Also, the required match is given at creation time : exact (IsEqual) or contains (the Type's Name must contain the criterium Text)
 CIFSelect_SelectSignedSharedIn the graph, explore the Shareds of the input entities, until it encounters some which match a given Signature (for a limited level, filters the returned list) By default, fitted for any level
 CIFSelect_SelectSignedSharingIn the graph, explore the sharings of the input entities, until it encounters some which match a given Signature (for a limited level, filters the returned list) By default, fitted for any level
 CIFSelect_SelectSuiteA SelectSuite can describe a suite of SelectDeduct as a unique one : in other words, it can be seen as a "macro selection"
 CIFSelect_SelectTypeA SelectType keeps or rejects Entities of which the Type is Kind of a given Cdl Type
 CIFSelect_SelectUnionA SelectUnion cumulates the Entities issued from several other Selections (union of results : "OR" operator)
 CIFSelect_SelectUnknownEntitiesA SelectUnknownEntities sorts the Entities which are qualified as "Unknown" (their Type has not been recognized)
 CIFSelect_SessionDumperA SessionDumper is called by SessionFile. It takes into account a set of classes (such as Selections, Dispatches ...). SessionFile writes the Type (as defined by cdl) of each Item and its general Parameters. It manages the names of the Items
 CIFSelect_SessionFileA SessionFile is intended to manage access between a WorkSession and an Ascii Form, to be considered as a Dump. It allows to write the File from the WorkSession, and later read the File to the WorkSession, by keeping required descriptions (such as dependances)
 CIFSelect_SessionPilotA SessionPilot is intended to make easier the use of a WorkSession. It receives commands, under alphanumeric form, then calls a library of Activators to interprete and run them

 CIFSelect_SignValidityThis Signature returns the Validity Status of an entity, as deducted from data in the model : it can be "OK" "Unknown" "Unloaded" "Syntactic Fail"(but loaded) "Syntactic Warning" "Semantic Fail" "Semantic Warning"
 CIFSelect_TransformerA Transformer defines the way an InterfaceModel is transformed (without sending it to a file). In order to work, each type of Transformer defines it method Perform, it can be parametred as needed
 CIFSelect_TransformStandardThis class runs transformations made by Modifiers, as the ModelCopier does when it produces files (the same set of Modifiers can then be used, as to transform the starting Model, as at file sending time)
 CIFSelect_WorkLibraryThis class defines the (empty) frame which can be used to enrich a XSTEP set with new capabilities In particular, a specific WorkLibrary must give the way for Reading a File into a Model, and Writing a Model to a File Thus, it is possible to define several Work Libraries for each norm, but recommanded to define one general class for each one : this general class will define the Read and Write methods
 CIFSelect_WorkSessionThis class can be used to simply manage a process such as splitting a file, extracting a set of Entities ... It allows to manage different types of Variables : Integer or Text Parameters, Selections, Dispatches, in addition to a ShareOut. To each of these variables, a unique Integer Identifier is attached. A Name can be attached too as desired

If for your computation you need to have B-spline curves with a minima of continuity it can be interesting to know between which knot values, a B-spline curve arc, has a continuity of given order. This algorithm computes the indexes of the knots where you should split the curve, to obtain arcs with a constant continuity given at the construction time. The splitting values are in the range [FirstUKnotValue, LastUKnotValue] (See class B-spline curve from package Geom).

 CMMgt_TSharedIntermediate class between Standard_Transient and descendants. The abstract class TShared is the root class of managed objects. TShared objects are managed by a memory manager based on reference counting. They have handle semantics. In other words, the reference counter is transparently incremented and decremented according to the scope of handles. When all handles, which reference a single object are out of scope, the reference counter becomes null and the object is automatically deleted. The deallocated memory is not given back to the system though. It is reclaimed for new objects of the same size. Warning This memory management scheme does not work for cyclic data structures. In such cases (with back pointers for example), you should interrupt the cycle in a class by using a full C++ pointer instead of a handle

 CPrecisionThe Precision package offers a set of functions defining precision criteria for use in conventional situations when comparing two numbers. Generalities It is not advisable to use floating number equality. Instead, the difference between numbers must be compared with a given precision, i.e. : Standard_Real x1, x2 ; x1 = ... x2 = ... If ( x1 == x2 ) ... should not be used and must be written as indicated below: Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... x2 = ... If ( Abs ( x1 - x2 ) < Precision ) ... Likewise, when ordering floating numbers, you must take the following into account : Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... ! a large number x2 = ... ! another large number If ( x1 < x2 - Precision ) ... is incorrect when x1 and x2 are large numbers ; it is better to write : Standard_Real x1, x2 ; Standard_Real Precision = ... x1 = ... ! a large number x2 = ... ! another large number If ( x2 - x1 > Precision ) ... Precision in Cas.Cade Generally speaking, the precision criterion is not implicit in Cas.Cade. Low-level geometric algorithms accept precision criteria as arguments. As a rule, they should not refer directly to the precision criteria provided by the Precision package. On the other hand, high-level modeling algorithms have to provide the low-level geometric algorithms that they call, with a precision criteria. One way of doing this is to use the above precision criteria. Alternatively, the high-level algorithms can have their own system for precision management. For example, the Topology Data Structure stores precision criteria for each elementary shape (as a vertex, an edge or a face). When a new topological object is constructed, the precision criteria are taken from those provided by the Precision package, and stored in the related data structure. Later, a topological algorithm which analyses these objects will work with the values stored in the data structure. Also, if this algorithm is to build a new topological object, from these precision criteria, it will compute a new precision criterion for the new topological object, and write it into the data structure of the new topological object. The different precision criteria offered by the Precision package, cover the most common requirements of geometric algorithms, such as intersections, approximations, and so on. The choice of precision depends on the algorithm and on the geometric space. The geometric space may be :

 CRWStlThis package contains the methods to be used in the Stereo Lithograpy Application. The main features of this application are ,starting from a Shape :
 CSegment
 CSelect3D_BVHPrimitiveContentThe purpose of this class is to provide a link between BVH_PrimitiveSet and Select3D_SensitiveSet instance to build BVH tree for set of sensitives
 CSelect3D_InteriorSensitivePointSetThis class handles the selection of arbitrary point set with internal type of sensitivity. The main principle is to split the point set given onto planar convex polygons and search for the overlap with one or more of them through traverse of BVH tree
 CSelect3D_Pnt
 CSelect3D_PointData
 CSelect3D_SensitiveBoxA framework to define selection by a sensitive box
 CSelect3D_SensitiveCircleA framework to define sensitive 3D arcs and circles. In some cases this class can raise Standard_ConstructionError and Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly

 CSelect3D_SensitiveEntityAbstract framework to define 3D sensitive entities. As the selection process uses the principle of a projection of 3D shapes onto a 2D view where nearness to a rectangle determines whether a shape is picked or not, all 3D shapes need to be converted into 2D ones in order to be selected
 CSelect3D_SensitiveFaceSensitive Entity to make a face selectable. In some cases this class can raise Standard_ConstructionError and Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly
 CSelect3D_SensitiveGroupA framework to define selection of a sensitive group by a sensitive entity which is a set of 3D sensitive entities. Remark: 2 modes are possible for rectangle selection the group is considered selected 1) when all the entities inside are selected in the rectangle 2) only one entity inside is selected by the rectangle By default the "Match All entities" mode is set
 CSelect3D_SensitivePointA framework to define sensitive 3D points
 CSelect3D_SensitivePolySensitive Entity to make a face selectable. In some cases this class can raise Standard_ConstructionError and Standard_OutOfRange exceptions from its member Select3D_PointData myPolyg
 CSelect3D_SensitiveSegmentA framework to define sensitive zones along a segment One gives the 3D start and end point
 CSelect3D_SensitiveSetThis class is base class for handling overlap detection of complex sensitive entities. It provides an interface for building BVH tree for some set of entities. Thereby, each iteration of overlap detection is a traverse of BVH tree in fact. To use speed-up hierarchical structure in a custom complex sensitive entity, it is necessary to make that custom entity a descendant of this class and organize sub-entities in some container which allows referencing to elements by index. Note that methods taking index as a parameter are used for BVH build and the range of given index is [0; Size() - 1]. For example of usage see Select3D_SensitiveTriangulation
 CSelect3D_SensitiveTriangleA framework to define selection of triangles in a view. This comes into play in the detection of meshing and triangulation in surfaces. In some cases this class can raise Standard_ConstructionError and Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly

 CSelectMgr_EntityOwnerA framework to define classes of owners of sensitive primitives. The owner is the link between application and selection data structures. For the application to make its own objects selectable, it must define owner classes inheriting this framework
 CSelectMgr_FilterThe root class to define filter objects for selection. Advance handling of objects requires the services of filters. These only allow dynamic detection and selection of objects which correspond to the criteria defined in each. Eight standard filters inheriting SelectMgr_Filter are defined in Open CASCADE. You can create your own filters by defining new filter classes inheriting this framework. You use these filters by loading them into an AIS interactive context
 CSelectMgr_FrustumThis is an internal class containing representation of rectangular selecting frustum, created in case of point and box selection, and algorithms for overlap detection between selecting frustum and sensitive entities. The principle of frustum calculation:
 CSelectMgr_FrustumBuilderThe purpose of this class is to provide unified interface for building selecting frustum depending on current camera projection and orientation matrices, window size and viewport parameters
 CSelectMgr_OrFilterA framework to define an or selection filter. This selects one or another type of sensitive entity
 CSelectMgr_RectangularFrustumThis class contains representation of rectangular selecting frustum, created in case of point and box selection, and algorithms for overlap detection between selecting frustum and sensitive entities. The principle of frustum calculation:
 CSelectMgr_SelectableObjectA framework to supply the structure of the object to be selected. At the first pick, this structure is created by calling the appropriate algorithm and retaining this framework for further picking. This abstract framework is inherited in Application Interactive Services (AIS), notably in AIS_InteractiveObject. Consequently, 3D selection should be handled by the relevant daughter classes and their member functions in AIS. This is particularly true in the creation of new interactive objects
 CSelectMgr_SelectableObjectSetThe purpose of this class is to organize all selectable objects into data structure, allowing to build BVH tree. For selectable objects binned BVH builder is used with 32 bins and 1 element per leaf
 CSelectMgr_SelectableObjectTrsfPersSetPrimitive set specialized for transformation persistent selectable objects. Provides built-in mechanism to invalidate tree when world view projection state changes. Due to frequent invalidation of BVH tree the choice of BVH tree builder is made in favor of BVH linear builder (quick rebuild)
 CSelectMgr_SelectingVolumeManagerThis class is used to switch between active selecting volumes depending on selection type chosen by the user
 CSelectMgr_SelectionRepresents the state of a given selection mode for a Selectable Object. Contains all the sensitive entities available for this mode. An interactive object can have an indefinite number of modes of selection, each representing a "decomposition" into sensitive primitives; each primitive has an Owner (SelectMgr_EntityOwner) which allows us to identify the exact entity which has been detected. Each Selection mode is identified by an index. The set of sensitive primitives which correspond to a given mode is stocked in a SelectMgr_Selection object. By Convention, the default selection mode which allows us to grasp the Interactive object in its entirety will be mode 0. AIS_Trihedron : 4 selection modes
 CSelectMgr_SelectionManagerA framework to manage selection from the point of view of viewer selectors. These can be added and removed, and selection modes can be activated and deactivated. In addition, objects may be known to all selectors or only to some
 CSelectMgr_SensitiveEntityThe purpose of this class is to mark sensitive entities selectable or not depending on current active selection of parent object for proper BVH traverse
 CSelectMgr_SensitiveEntitySetThis class is used to store all calculated sensitive entites of one selectable object. It provides an interface for building BVH tree which is used to speed-up the performance of searching for overlap among sensitives of one selectable object
 CSelectMgr_SortCriterionThis class provides data and criterion for sorting candidate entities in the process of interactive selection by mouse click
 CSelectMgr_ToleranceMapAn internal class for calculation of current largest tolerance value which will be applied for creation of selecting frustum by default. Each time the selection set is deactivated, maximum tolerance value will be recalculated. If a user enables custom precision using StdSelect_ViewerSelector3d::SetPixelTolerance, it will be applied to all sensitive entities without any checks
 CSelectMgr_TriangularFrustumThis class contains representation of triangular selecting frustum, created in case of polyline selection, and algorithms for overlap detection between selecting frustum and sensitive entities. Overlap detection tests are implemented according to the terms of separating axis theorem (SAT)
 CSelectMgr_TriangularFrustumSetThis class is used to handle polyline selection. The main principle of polyline selection algorithm is to split the polygon defined by polyline onto triangles. Than each of them is considered as a base for triangular frustum building. In other words, each triangle vertiex will be projected from 2d screen space to 3d world space onto near and far view frustum planes. Thus, the projected triangles make up the bases of selecting frustum. When the set of such frustums is created, the function determining selection iterates through triangular frustum set and searches for overlap with any frustum
 CSelectMgr_ViewClipRangeClass for handling depth clipping range. It is used to perform checks in case if global (for the whole view) clipping planes are defined inside of SelectMgr_RectangularFrustum class methods
 CSelectMgr_ViewerSelectorA framework to define finding, sorting the sensitive primitives in a view. Services are also provided to define the return of the owners of those primitives selected. The primitives are sorted by criteria such as priority of the primitive or its depth in the view relative to that of other primitives. Note that in 3D, the inheriting framework StdSelect_ViewerSelector3d is only to be used if you do not want to use the services provided by AIS. Two tools are available to find and select objects found at a given position in the view. If you want to select the owners of all the objects detected at point x,y,z you use the Init - More - Next - Picked loop. If, on the other hand, you want to select only one object detected at that point, you use the Init - More - OnePicked loop. In this iteration, More is used to see if an object was picked and OnePicked, to get the object closest to the pick position. Viewer selectors are driven by SelectMgr_SelectionManager, and manipulate the SelectMgr_Selection objects given to them by the selection manager

 CStorage_CallBack
 CStorage_DataA picture memorizing the data stored in a container (for example, in a file). A Storage_Data object represents either:
 CStorage_DefaultCallBack
 CStorage_HeaderData
 CStorage_InternalData
 CStorage_RootA root object extracted from a Storage_Data object. A Storage_Root encapsulates a persistent object which is a root of a Storage_Data object. It contains additional information: the name and the data type of the persistent object. When retrieving a Storage_Data object from a container (for example, a file) you access its roots with the function Roots which returns a sequence of root objects. The provided functions allow you to request information about each root of the sequence. You do not create explicit roots: when inserting data in a Storage_Data object, you just provide the persistent object and optionally its name to the function AddRoot

 CTransfer_TransientProcessAdds specific features to the generic definition : TransientProcess is intended to work from an InterfaceModel to a set of application objects
 CTransfer_VoidBinderVoidBinder is used to bind a starting item with a status, error or warning messages, but no result It is interpreted by TransferProcess, which admits a VoidBinder to be over-written, and copies its check to the new Binder
 CTransferBRepThis package gathers services to simply read files and convert them to Shapes from CasCade. IE. it can be used in conjunction with purely CasCade software
 CTransferBRep_BinderOfShapeAllows direct binding between a starting Object and the Result of its transfer when it is Unique. The Result itself is defined as a formal parameter <Shape from="" topods>=""> Warning : While it is possible to instantiate BinderOfShape with any Type for the Result, it is not advisable to instantiate it with Transient Classes, because such Results are directly known and managed by TransferProcess & Co, through SimpleBinderOfTransient : this class looks like instantiation of BinderOfShape, but its method ResultType is adapted (reads DynamicType of the Result)
 CTransferBRep_OrientedShapeMapper
 CTransferBRep_ReaderThis class offers a simple, easy to call, way of transferring data from interface files to Shapes from CasCade It must be specialized according to each norm/protocol, by :

 CVrml_IndexedFaceSetDefines a IndexedFaceSet node of VRML specifying geometry shapes. This node represents a 3D shape formed by constructing faces (polygons) from vertices located at the current coordinates. IndexedFaceSet uses the indices in its coordIndex to define polygonal faces. An index of -1 separates faces (so a -1 at the end of the list is optional)
 CVrml_IndexedLineSetDefines a IndexedLineSet node of VRML specifying geometry shapes. This node represents a 3D shape formed by constructing polylines from vertices located at the current coordinates. IndexedLineSet uses the indices in its coordIndex field to specify the polylines. An index of -1 separates one polyline from the next (thus, a final -1 is optional). the current polyline has ended and the next one begins. Treatment of the current material and normal binding is as follows: The PER_PART binding specifies a material or normal for each segment of the line. The PER_FACE binding specifies a material or normal for each polyline. PER_VERTEX specifies a material or normal for each vertex. The corresponding _INDEXED bindings are the same, but use the materialIndex or normalIndex indices. The DEFAULT material binding is equal to OVERALL. The DEFAULT normal binding is equal to PER_VERTEX_INDEXED; if insufficient normals exist in the state, the lines will be drawn unlit. The same rules for texture coordinate generation as IndexedFaceSet are used

 CVrml_InstancingDefines "instancing" - using the same instance of a node multiple times. It is accomplished by using the "DEF" and "USE" keywords. The DEF keyword both defines a named node, and creates a single instance of it. The USE keyword indicates that the most recently defined instance should be used again. If several nades were given the same name, then the last DEF encountered during parsing "wins". DEF/USE is limited to a single file
 CVrml_LODDefines a LOD (level of detailization) node of VRML specifying properties of geometry and its appearance.

To bind materials to shapes, use a MaterialBinding node
 CVrml_MaterialBindingDefines a MaterialBinding node of VRML specifying properties of geometry and its appearance. Material nodes may contain more than one material. This node specifies how the current materials are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently. For example, a Sphere node is always drawn using the first material in the material node, no matter what the current MaterialBinding, while a Cube node may use six different materials to draw each of its six faces, depending on the MaterialBinding
 CVrml_MatrixTransformDefines a MatrixTransform node of VRML specifying matrix and transform properties. This node defines 3D transformation with a 4 by 4 matrix. By default : a11=1 a12=0 a13=0 a14=0 a21=0 a22=1 a23=0 a24=0 a31=0 a32=0 a33=1 a34=0 a41=0 a42=0 a43=0 a44=1 It is written to the file in row-major order as 16 Real numbers separated by whitespace. For example , matrix expressing a translation of 7.3 units along the X axis is written as: 1 0 0 0 0 1 0 0 0 0 1 0 7.3 0 0 1
 CVrml_NormalDefines a Normal node of VRML specifying properties of geometry and its appearance. This node defines a set of 3D surface normal vectors to be used by vertex-based shape nodes (IndexedFaceSet, IndexedLineSet, PointSet) that follow it in the scene graph. This node does not produce a visible result during rendering; it simply replaces the current normals in the rendering state for subsequent nodes to use. This node contains one multiple-valued field that contains the normal vectors
 CVrml_NormalBindingDefines a NormalBinding node of VRML specifying properties of geometry and its appearance. This node specifies how the current normals are bound to shapes that follow in the scene graph. Each shape node may interpret bindings differently. The bindings for faces and vertices are meaningful only for shapes that are made from faces and vertices. Similarly, the indexed bindings are only used by the shapes that allow indexing. For bindings that require multiple normals, be sure to have at least as many normals defined as are necessary; otherwise, errors will occur

This group node performs a push (save) of the traversal state before traversing its children and a pop (restore) after traversing them. This isolates the separator's children from the rest of the scene graph. A separator can include lights, cameras, coordinates, normals, bindings, and all other properties. Separators can also perform render culling. Render culling skips over traversal of the separator's children if they are not going to be rendered, based on the comparison of the separator's bounding box with the current view volume. Culling is controlled by the renderCulling field. These are set to AUTO by default, allowing the implementation to decide whether or not to cull
 CVrml_SFImageDefines SFImage type of VRML field types
 CVrml_SFRotationDefines SFRotation type of VRML field types. The 4 values represent an axis of rotation followed by amount of right-handed rotation about the that axis, in radians
 CVrml_ShapeHintsDefines a ShapeHints node of VRML specifying properties of geometry and its appearance. The ShapeHints node indicates that IndexedFaceSets are solid, contain ordered vertices, or contain convex faces. These hints allow VRML implementations to optimize certain rendering features. Optimizations that may be performed include enabling back-face culling and disabling two-sided lighting. For example, if an object is solid and has ordered vertices, an implementation may turn on backface culling and turn off two-sided lighting. To ensure that an IndexedFaceSet can be viewed from either direction, set shapeType to be UNKNOWN_SHAPE_TYPE. If you know that your shapes are closed and will alwsys be viewed from the outside, set vertexOrdering to be either CLOCKWISE or COUNTERCLOCKWISE (depending on how you built your object), and set shapeType to be SOLID. Placing this near the top of your VRML file will allow the scene to be rendered much faster. The ShapeHints node also affects how default normals are generated. When an IndexedFaceSet has to generate default normals, it uses the creaseAngle field to determine which edges should be smoothly shaded and which ones should have a sharp crease. The crease angle is the angle between surface normals on adjacent polygons. For example, a crease angle of .5 radians (the default value) means that an edge between two adjacent polygonal faces will be smooth shaded if the normals to the two faces form an angle that is less than .5 radians (about 30 degrees). Otherwise, it will be faceted
 CVrml_SphereDefines a Sphere node of VRML specifying geometry shapes. This node represents a sphere. By default , the sphere is centred at (0,0,0) and has a radius of 1
 CVrml_SpotLightSpot light node of VRML nodes specifying properties of lights. This node defines a spotlight light source. A spotlight is placed at a fixed location in 3D-space and illuminates in a cone along a particular direction. The intensity of the illumination drops off exponentially as a ray of light diverges from this direction toward the edges of cone. The rate of drop-off and agle of the cone are controlled by the dropOfRate and cutOffAngle Color is written as an RGB triple. Light intensity must be in the range 0.0 to 1.0, inclusive
 CVrml_SwitchDefines a Switch node of VRML specifying group properties. This group node traverses one, none, or all of its children. One can use this node to switch on and off the effects of some properties or to switch between different properties. The whichChild field specifies the index of the child to traverse, where the first child has index 0. A value of -1 (the default) means do not traverse any children. A value of -3 traverses all children, making the switch behave exactly like a regular Group
 CVrml_Texture2Defines a Texture2 node of VRML specifying properties of geometry and its appearance. This property node defines a texture map and parameters for that map The texture can be read from the URL specified by the filename field. To turn off texturing, set the filename field to an empty string (""). Textures can alsobe specified inline by setting the image field to contain the texture data. By default : myFilename ("") myImage (0 0 0) myWrapS (Vrml_REPEAT) myWrapT (Vrml_REPEAT)
 CVrml_Texture2TransformDefines a Texture2Transform node of VRML specifying properties of geometry and its appearance. This node defines a 2D transformation applied to texture coordinates. This affect the way textures are applied to the surfaces of subsequent shapes. Transformation consisits of(in order) a non-uniform scale about an arbitrary center point, a rotation about that same point, and a translation. This allows a user to change the size and position of the textures on the shape. By default : myTranslation (0 0) myRotation (0) myScaleFactor (1 1) myCenter (0 0)
 CVrml_TextureCoordinate2Defines a TextureCoordinate2 node of VRML specifying properties of geometry and its appearance. This node defines a set of 2D coordinates to be used to map textures to the vertices of subsequent PointSet, IndexedLineSet, or IndexedFaceSet objects. It replaces the current texture coordinates in the rendering state for the shapes to use. Texture coordinates range from 0 to 1 across the texture. The horizontal coordinate, called S, is specified first, followed by vertical coordinate, T. By default : myPoint (0 0)
 CVrml_TransformDefines a Transform of VRML specifying transform properties. This node defines a geometric 3D transformation consisting of (in order) a (possibly) non-uniform scale about an arbitrary point, a rotation about an arbitrary point and axis and translation. By default : myTranslation (0,0,0) myRotation (0,0,1,0) myScaleFactor (1,1,1) myScaleOrientation (0,0,1,0) myCenter (0,0,0)
 CVrml_TransformSeparatorDefines a TransformSeparator node of VRML specifying group properties. This group node is similar to separator node in that it saves state before traversing its children and restores it afterwards. This node can be used to isolate transformations to light sources or objects
 CVrml_TranslationDefines a Translation of VRML specifying transform properties. This node defines a translation by 3D vector. By default : myTranslation (0,0,0)
 CVrml_WWWAnchorDefines a WWWAnchor node of VRML specifying group properties. The WWWAnchor group node loads a new scene into a VRML browser when one of its children is closen. Exactly how a user "chooses" a child of the WWWAnchor is up to the VRML browser. WWWAnchor with an empty ("") name does nothing when its children are chosen. WWWAnchor behaves like a Separator, pushing the traversal state before traversing its children and popping it afterwards
 CVrml_WWWInlineDefines a WWWInline node of VRML specifying group properties. The WWWInline group node reads its children from anywhere in the World Wide Web. Exactly when its children are read is not defined; reading the children may be delayed until the WWWInline is actually displayed. WWWInline with an empty ("") name does nothing. WWWInline behaves like a Separator, pushing the traversal state before traversing its children and popping it afterwards. By defaults: myName ("") myBboxSize (0,0,0) myBboxCenter (0,0,0)

 CWNT_WClassThis class defines a Windows NT window class. A window in Windows NT is always created based on a window class. The window class identifies the window procedure that processes messages to the window. Each window class has unique name ( character string ). More than one window can be created based on a single window class. For example, all button windows in Windows NT are created based on the same window class. The window class defines the window procedure and some other characteristics ( background, mouse cursor shape etc. ) of the windows that are created based on that class. When we create a window, we define additional characteristics of the window that are unique to that window. So, we have to create and register window class before creation of any window. Of course, it's possible to create a new window class for each window inside the Window class and do not use the WClass at all. We implemented this class for sake of flexibility of event processing

 CXCAFDoc_ShapeMapToolAttribute containing map of sub shapes
 CXCAFDoc_ShapeToolA tool to store shapes in an XDE document in the form of assembly structure, and to maintain this structure. Attribute containing Shapes section of DECAF document. Provide tools for management of Shapes section. The API provided by this class allows to work with this structure regardless of its low-level implementation. All the shapes are stored on child labels of a main label which is XCAFDoc_DocumentTool::LabelShapes(). The label for assembly also has sub-labels, each of which represents the instance of another shape in that assembly (component). Such sub-label stores reference to the label of the original shape in the form of TDataStd_TreeNode with GUID XCAFDoc::ShapeRefGUID(), and its location encapsulated into the NamedShape. For correct work with an XDE document, it is necessary to use methods for analysis and methods for working with shapes. For example: if ( STool->IsAssembly(aLabel) ) { Standard_Boolean subchilds = Standard_False; (default) Standard_Integer nbc = STool->NbComponents (aLabel[,subchilds]); } If subchilds is True, commands also consider sub-levels. By default, only level one is checked. In this example, number of children from the first level of assembly will be returned. Methods for creation and initialization: Constructor: XCAFDoc_ShapeTool::XCAFDoc_ShapeTool() Getting a guid: Standard_GUID GetID (); Creation (if does not exist) of ShapeTool on label L: Handle(XCAFDoc_ShapeTool) XCAFDoc_ShapeTool::Set(const TDF_Label& L) Analyze whether shape is a simple shape or an instance or a component of an assembly or it is an assembly ( methods of analysis). For example: STool->IsShape(aLabel) ; Analyze that the label represents a shape (simple shape, assembly or reference) or STool->IsTopLevel(aLabel); Analyze that the label is a label of a top-level shape. Work with simple shapes, assemblies and instances ( methods for work with shapes). For example: Add shape: Standard_Boolean makeAssembly; // True to interpret a Compound as an Assembly, False to take it as a whole aLabel = STool->AddShape(aShape, makeAssembly); Get shape: TDF_Label aLabel... // A label must be present if (aLabel.IsNull()) { ... no such label : abandon .. } TopoDS_Shape aShape; aShape = STool->GetShape(aLabel); if (aShape.IsNull()) { ... this label is not for a Shape ... } To get a label from shape. Standard_Boolean findInstance = Standard_False; (this is default value) aLabel = STool->FindShape(aShape [,findInstance]); if (aLabel.IsNull()) { ... no label found for this shape ... }
