The NDD_INSTANCE structures are used for processing instances in nd. They enable the realization of NULL, object, animation, and timekeeper instance data, as well as scene hierarchy links.
By registering scene and object structures in NDD_INSTANCE and calling the ndEvalInstance() function, the hierarchical structure from the scene can be evaluated.
A new structure for texture coordinate animation, NDD_INST_DEFORM_VTXST, was added to this version.
