Abstract interface to scene data.
Hydra ExtComputations provide a simple computation framework allowing primvars to be computed using C...
HDSI_API HdSceneIndexPrim GetPrim(const SdfPath &primPath) const override final
Returns a pair of (prim type, datasource) for the object at primPath.
HDSI_API SdfPathVector GetChildPrimPaths(const SdfPath &primPath) const override final
Returns the paths of all scene index prims located immediately below primPath.
A path value used to locate objects in layers or scenegraphs.
#define TF_DECLARE_WEAK_AND_REF_PTRS(type)
Define standard weak, ref, and vector pointer types.
