Hydra ExtComputations provide a simple computation framework allowing primvars to be computed using CPU or GPU kernels.
Computed primvars backed by CPU kernels are evaluated during the Hydra sync phase. This disallows transformations on the computed values via scene indices. This scene index alleviates this by pruning computed primvars and presenting them as authored primvars. The computation is executed when pulling on the primvar's value. Thus, scene indices downstream that take this as an input can transform the (computed) primvar data just like any authored primvar.

finaloverridevirtual |
Returns the paths of all scene index prims located immediately below primPath.
This function can be used to traverse the scene by recursing from SdfPath::AbsoluteRootPath(); such a traversal is expected to give the same set of prims as the flattening of the scene index's PrimsAdded and PrimsRemoved messages. This function is expected to be threadsafe.
Implements HdSceneIndexBase.

finaloverridevirtual |
Returns a pair of (prim type, datasource) for the object at primPath.
If no such object exists, the type will be the empty token and the datasource will be null. This function is expected to be threadsafe.
Implements HdSceneIndexBase.
