typedef void(* | UniqueChangedFuncPtr )(TfRefBase const *, bool) |
Merges multiple scenes together. For prims which exist in more than one input scene, data sources are overlayed (down to the leaf) with the earlier inserted scene having the stronger opinion. NOTE: This is currently the only example of a multi-input scene index and therefore that pattern hasn't yet been broken into a base class.

HD_API void HdMergingSceneIndex::AddInputScene | ( | const HdSceneIndexBaseRefPtr & | inputScene, |
const SdfPath & | activeInputSceneRoot | ||
) |
Adds a scene with activeInputSceneRoot specifying the shallowest path at which prims should be considered. This is an optional optimization to avoid having to query multiple inputs when it's known in advance which might be relevant for a given prim.
|
overridevirtual |
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.

overridevirtual |
satisfying HdFilteringSceneIndex
Implements HdFilteringSceneIndexBase.
|
overridevirtual |
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.
