Detailed Description

A primitive (see I3DExGeometricPrimitive) can derive from this interface when it is composed of multiple identical parts. For example a tree in which leaves are stored as instances. This allow storing the geometry of each object type only once. Note that you will need to provide your own Ray tracing implementation for this primitive (see IRaytracablePrimitive).

Member Function Documentation

virtual void MCCOMAPI I3DExInstancePrimitive::GetInstanceList (  uint32  instanceKind, TInstanceList **  instanceList )  [pure virtual]

Returns the list of instances for a given object Parameters: instanceKind  A 0-based index that identifies the object (the number of objects is defined by GetObjectNumber()) instanceList  A pointer (counted) to the instance list that is returned.

virtual void MCCOMAPI I3DExInstancePrimitive::GetInstanceMesh (  uint32  instanceKind, FacetMesh **  mesh )  [pure virtual]

Returns the mesh for a given object. Parameters: instanceKind  A 0-based index that identifies the object (the number of objects is defined by GetObjectNumber()) mesh  A pointer to the facet mesh that is returned.

virtual uint32 MCCOMAPI I3DExInstancePrimitive::GetObjectNumber (   )  [pure virtual]

Returns the number of "template" objects being instanciated in the primitive
