Defines 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. More...

virtual AIS_KindOfInteractive	Type () const
	Returns the kind of Interactive Object: More...

virtual Standard_Integer	Signature () const
	Specifies additional characteristics of Interactive Objects. A signature is, in fact, an index with integer values assigned different properties. This method is frequently used in conjuction with Type to give a particular type and signature to an Interactive Object. By default, the Interactive Object has a None type and a signature of 0. Among the datums, this signature is attributed to the shape The remaining datums have the following default signatures: More...

virtual Standard_Boolean	AcceptShapeDecomposition () const
	Informs the graphic context that the interactive Object may be decomposed into sub-shapes for dynamic selection. The most used Interactive Object is AIS_Shape. Activation methods for standard selection modes are proposed in the Interactive Context. These include selection by vertex or by edges. For datums with the same behavior as AIS_Shape, such as vetices and edges, we must redefine the virtual method so that AcceptShapeDecomposition returns false. Rule for selection : Mode 0 : Selection of the interactive Object itself Mode 1 : Selection of vertices Mode 2 : Selection Of Edges Mode 3 : Selection Of Wires Mode 4 : Selection Of Faces ...

Detailed Description

Defines 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.

The TypeOfPresention3d means that the interactive object may have a presentation dependant of the view of Display.

Member Function Documentation

virtual Standard_Boolean AIS_InteractiveObject::AcceptDisplayMode ( const Standard_Integer aMode ) const

virtual

Returns true if the class of objects accepts the display mode aMode. The interactive context can have a default mode of representation for the set of Interactive Objects. This mode may not be accepted by a given class of objects. Consequently, this virtual method allowing us to get information about the class in question must be implemented.

Reimplemented in AIS_Dimension, AIS_Relation, AIS_Plane, AIS_Trihedron, AIS_Axis, AIS_PlaneTrihedron, and AIS_Point.

virtual Standard_Boolean AIS_InteractiveObject::AcceptShapeDecomposition ( ) const

virtual

Informs the graphic context that the interactive Object may be decomposed into sub-shapes for dynamic selection. The most used Interactive Object is AIS_Shape. Activation methods for standard selection modes are proposed in the Interactive Context. These include selection by vertex or by edges. For datums with the same behavior as AIS_Shape, such as vetices and edges, we must redefine the virtual method so that AcceptShapeDecomposition returns false. Rule for selection : Mode 0 : Selection of the interactive Object itself Mode 1 : Selection of vertices Mode 2 : Selection Of Edges Mode 3 : Selection Of Wires Mode 4 : Selection Of Faces ...

Reimplemented in AIS_ConnectedInteractive, AIS_MultipleConnectedInteractive, and AIS_Shape.

Standard_Boolean AIS_InteractiveObject::HasPresentation ( ) const

Returns TRUE when this object has a presentation in the current DisplayMode()

Standard_Boolean AIS_InteractiveObject::HasSelectionMode ( ) const

Allows you to change the selection mode of an Interactive Object. The default selection mode setting is 0. For shapes, for example, the selection modes are as follows:

mode 0 - selection of the shape itself
mode 1 - selection of vertices
mode 2 - selection of edges
mode 3 - selection of wires
mode 4 - selection of faces
mode 5 - selection of shells
mode 6 - selection of solids
mode 7 - selection of compounds For trihedra, on the other hand, the selection modes are the following four:
mode 0 - selection of a trihedron
mode 1 - selection of its origin
mode 2 - selection of its axes
mode 3 - selection of its planes

Standard_Boolean AIS_InteractiveObject::HasSelectionPriority ( ) const

Returns true if there is a setting for selection priority. You can modify selection priority of an owner to make one entity more selectionable than another one. The default selection priority for an owner is 5, for example. To increase selection priority, choose a setting between 5 and 10. An entity with priority 7 will take priority over one with a setting of 6.

Standard_Boolean AIS_InteractiveObject::HasUsers ( ) const

Standard_Boolean AIS_InteractiveObject::HasWidth ( ) const

Returns true if the Interactive Object has width.

Standard_Integer AIS_InteractiveObject::HilightMode ( ) const

Returns the setting for highlight mode. At dynamic detection, the presentation echoed by the Interactive Context, is by default the presentation already on the screen. You can specify a Highlight presentation mode which is valid no matter what the active representation of the object. It makes no difference whether this choice is temporary or definitive. To do this, we use the following functions:

SetHilightMode
UnSetHilightMode In the case of a shape, whether it is visualized in wireframe presentation or with shading, we want to systematically highlight the wireframe presentation. Consequently, we set the highlight mode to 0.

Standard_Boolean AIS_InteractiveObject::IsInfinite ( ) const

Returns true if the interactive object is infinite. In this case, its graphic presentations are not taken into account in the fit-all view.

Standard_Boolean AIS_InteractiveObject::IsTransparent ( ) const

void AIS_InteractiveObject::Redisplay ( const Standard_Boolean AllModes = Standard_False )

Updates the active presentation; if <AllModes> = Standard_True all the presentations inside are recomputed. IMPORTANT: It is preferable to call Redisplay method of corresponding AIS_InteractiveContext instance for cases when it is accessible. This method just redirects call to myCTXPtr, so this class field must be up to date for proper result.

Standard_Integer AIS_InteractiveObject::SelectionMode ( ) const

Returns the selection mode of the interactive object.

Standard_Integer AIS_InteractiveObject::SelectionPriority ( ) const

Returns the selection priority setting. -1 indicates that there is none. You can modify the selection priority of an owner to make one entity more selectionable than another one. The default selection priority for an owner is 5, for example. To increase selection priority, choose a setting between 5 and 10. An entity with priority 7 will take priority over one with a setting of 6 if both objects are selected at the same time. You could give vertices priority 8, edges priority 7, faces priority 6, and shapes priority 5. If a vertex, an edge and a face are simultaneously detected during selection, only the vertex will then be highlighted. For trihedra, for example, the default priorities are the following four:

priority 1 - a trihedron
priority 5 - its origin
priority 3 - its axes
priority 2 - its planes

void AIS_InteractiveObject::SetAspect	(	const Handle< Prs3d_BasicAspect > &	anAspect,
		const Standard_Boolean	globalChange = `Standard_True`

virtual

only the interactive obj knowns which Drawer attribute is affected by the color (ex: for a wire, it's the wireaspect field of the drawer, but for a vertex, only the point aspect field is affected by the color) WARNING : Do not forget to set the corresponding fields here (hasOwnColor and myOwnColor)

Reimplemented in AIS_Shape, AIS_Plane, AIS_Trihedron, AIS_Axis, AIS_PlaneTrihedron, AIS_PointCloud, AIS_Circle, AIS_Line, AIS_Point, AIS_Relation, and AIS_TextLabel.

virtual void AIS_InteractiveObject::SetContext ( const Handle< AIS_InteractiveContext > & aCtx )

Reimplemented in AIS_Plane, and AIS_Trihedron.

void AIS_InteractiveObject::SetCurrentFacingModel ( const Aspect_TypeOfFacingModel aModel = Aspect_TOFM_BOTH_SIDE )

change the current facing model apply on polygons for SetColor(), SetTransparency(), SetMaterial() methods default facing model is Aspect_TOFM_TWO_SIDE. This mean that attributes is applying both on the front and back face.

void AIS_InteractiveObject::SetDisplayMode ( const Standard_Integer aMode )

Sets the display mode aMode for the interactive object. An object can have its own temporary display mode, which is different from that proposed by the interactive context. The range of possibilities currently proposed is the following:

AIS_WireFrame
AIS_Shaded This range can, however, be extended through the creation of new display modes.

void AIS_InteractiveObject::SetHilightMode ( const Standard_Integer anIndex )

Sets the highlight mode anIndex for the interactive object. If, for example, you want to systematically highlight the wireframe presentation of a shape - whether visualized in wireframe presentation or with shading - you set the highlight mode to 0.

void AIS_InteractiveObject::SetInfiniteState ( const Standard_Boolean aFlag = Standard_True )

Sets the infinite state flag aFlage. if <aFlag> = True , the interactiveObject is considered as infinite, i.e. its graphic presentations are not taken in account for View FitAll...

virtual void AIS_InteractiveObject::SetMaterial ( const Graphic3d_NameOfMaterial aName )

virtual

Sets the name aName for material defining this display attribute for the interactive object. Material aspect determines shading aspect, color and transparency of visible entities.

Reimplemented in AIS_Shape, and AIS_PointCloud.

virtual void AIS_InteractiveObject::SetMaterial ( const Graphic3d_MaterialAspect & aName )

virtual

Sets the material aMat defining this display attribute for the interactive object. Material aspect determines shading aspect, color and transparency of visible entities.

void AIS_InteractiveObject::SetOwner ( const Handle< Standard_Transient > & ApplicativeEntity )

Allows you to attribute the owner ApplicativeEntity to an Interactive Object. This can be a shape for a set of sub-shapes or a sub-shape for sub-shapes which it is composed of. The owner takes the form of a transient.

virtual void AIS_InteractiveObject::SetPolygonOffsets	(	const Standard_Integer	aMode,
		const Standard_ShortReal	aFactor = `1.0`,
		const Standard_ShortReal	aUnits = `0.0`
	)

virtual

Sets up polygon offsets for this object. It modifies all existing presentations of <anObj> (if any), so it is reasonable to call this method after <anObj> has been displayed. Otherwise, Compute() method should pass Graphic3d_AspectFillArea3d aspect from <myDrawer> to Graphic3d_Group to make polygon offsets work.

<aMode> parameter can contain various combinations of Aspect_PolygonOffsetMode enumeration elements (Aspect_POM_None means that polygon offsets are not changed). If <aMode> is different from Aspect_POM_Off and Aspect_POM_None, then <aFactor> and <aUnits> arguments are used by graphic renderer to calculate a depth offset value:

offset = <aFactor> * m + <aUnits> * r, where m - maximum depth slope for the polygon currently being displayed, r - minimum window coordinates depth resolution (implementation-specific).

Deafult settings for OCC 3D viewer: mode = Aspect_POM_Fill, factor = 1., units = 0.

Negative offset values move polygons closer to the viewport, while positive values shift polygons away. Consult OpenGL reference for details (glPolygonOffset function description).

NOTE: This method has a side effect - it creates own shading aspect if not yet created, so it is better to set up object material, color, etc. first.

void AIS_InteractiveObject::SetSelectionMode ( const Standard_Integer aMode )

You can change the default selection mode index aMode of an Interactive Object. This is only of interest if you decide that mode 0 adopted by convention will not do.

void AIS_InteractiveObject::SetSelectionPriority ( const Standard_Integer aPriority )

Allows you to provide a setting aPriority for selection priority. You can modify selection priority of an owner to make one entity more selectionable than another one. The default selection priority for an owner is 5, for example. To increase selection priority, choose a setting between 5 and 10. An entity with priority 7 will take priority over one with a setting of 6.

virtual void AIS_InteractiveObject::SetTransparency ( const Standard_Real aValue = 0.6 )

virtual

Attributes a setting aValue for transparency. The transparency value should be between 0.0 and 1.0. At 0.0 an object will be totally opaque, and at 1.0, fully transparent. Warning At a value of 1.0, there may be nothing visible.

Reimplemented in AIS_Shape, AIS_ColoredShape, and Voxel_Prs.

virtual Standard_Integer AIS_InteractiveObject::Signature ( ) const

virtual

Specifies additional characteristics of Interactive Objects. A signature is, in fact, an index with integer values assigned different properties. This method is frequently used in conjuction with Type to give a particular type and signature to an Interactive Object. By default, the Interactive Object has a None type and a signature of 0. Among the datums, this signature is attributed to the shape The remaining datums have the following default signatures:

Point signature 1
