Detailed Description

A framework to supply the Graphic3d structure of the object to be presented. On the first display request, this structure is created by calling the appropriate algorithm and retaining this framework for further display. This abstract framework is inherited in Application Interactive Services (AIS), notably by AIS_InteractiveObject. Consequently, 3D presentation 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.

Key interface methods to be implemented by every Selectable Object:

Warning! Methods managing standard attributes (SetColor(), SetWidth(), SetMaterial()) have different meaning for objects of different type (or no meaning at all). Sub-classes might override these methods to modify Prs3d_Drawer or class properties providing a convenient short-cut depending on application needs. For more sophisticated configuring, Prs3d_Drawer should be modified directly, while short-cuts might be left unimplemented.

Member Function Documentation

◆ AcceptDisplayMode()

virtual Standard_Boolean PrsMgr_PresentableObject::AcceptDisplayMode ( const Standard_Integer  theMode) const
inlinevirtual

Returns true if the class of objects accepts specified display mode index. 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. At least one display mode index should be accepted by this method. Although subclass can leave default implementation, it is highly desired defining exact list of supported modes instead, which is usually an enumeration for one object or objects class sharing similar list of display modes.

Reimplemented in AIS_ViewCube, AIS_ColorScale, AIS_Dimension, AIS_TexturedShape, AIS_Relation, AIS_Plane, AIS_Trihedron, AIS_ConnectedInteractive, AIS_Axis, AIS_Shape, AIS_PlaneTrihedron, AIS_MediaPlayer, AIS_CameraFrustum, AIS_Point, and MeshVS_Mesh.

◆ AddChild()

virtual void PrsMgr_PresentableObject::AddChild ( const Handle< PrsMgr_PresentableObject > &  theObject)

◆ AddChildWithCurrentTransformation()

void PrsMgr_PresentableObject::AddChildWithCurrentTransformation ( const Handle< PrsMgr_PresentableObject > &  theObject)

Makes theObject child of current object in scene hierarchy with keeping the current global transformation So the object keeps the same position/orientation in the global CS.

◆ AddClipPlane()

virtual void PrsMgr_PresentableObject::AddClipPlane ( const Handle< Graphic3d_ClipPlane > &  thePlane)
virtual

Adds clip plane for graphical clipping for all display mode presentations. The composition of clip planes truncates the rendering space to convex volume. Please be aware that number of supported clip plane is limited. The planes which exceed the limit are ignored. Besides of this, some planes can be already set in view where the object is shown: the number of these planes should be subtracted from limit to predict the maximum possible number of object clipping planes.

Parameters
thePlane[in] the clip plane to be appended to map of clip planes.

inline

Returns the attributes settings.

◆ BoundingBox()

virtual void PrsMgr_PresentableObject::BoundingBox ( Bnd_Box theBndBox)
virtual

Returns bounding box of object correspondingly to its current display mode. This method requires presentation to be already computed, since it relies on bounding box of presentation structures, which are supposed to be same/close amongst different display modes of this object.

◆ Children()

const PrsMgr_ListOfPresentableObjects& PrsMgr_PresentableObject::Children ( ) const
inline

Returns children of the current object.

◆ ClipPlanes()
