Validity Interval Methods

Object::ObjectValidity(TimeValue t)
Object::UpdateValidity(int nchan, Interval v)

Shapes Within Objects

Shape viewports can reference shapes contained within objects, so the system needs to be able to access the shapes within an object. The following four methods provide this access. These methods are used by the loft object. Since loft objects are made up of shapes, this gives the system the ability to query the object to find out if it is a shape container. Most objects don't contain shapes so they can just use the default implementations.
Object::NumberOfContainedShapes()
Object::GetContainedShape(TimeValue t, int index)
Object::GetContainedShapeMatrix(TimeValue t, int index, Matrix3 &mat)
Object::ContainedShapeSelectionArray()

Object Integrity Checking

Object::CheckObjectIntegrity()

Sub-Object Selection

Object::GetSubselState()

Data Flow Evaluation Methods

Most plug-in procedural objects do not need to be concerned with the following methods associated with locks, channels and shallow copies. The only type of plug-ins that needs to be concerned with these methods are objects that actually flow down the pipeline. Most procedural plug-ins don't go down the pipeline, instead they convert themselves to a TriObject or PatchObject, and these goes down the pipeline. It is these TriObjects or PatchObject that deal with these methods. However plug-in objects that actually flow down the pipeline will use these methods. For more information see the Advanced Topics section on the Geometry Pipeline System.
