Detailed Description

A scene index consuming a UsdStage.

This scene index does not perform any transformations such as flattening visibility or transforms or aggregate native instances. Use UsdImagingCreateSceneIndices to get a chain of scene indices to resolve those.

Member Function Documentation

USDIMAGING_API void UsdImagingStageSceneIndex::ApplyPendingUpdates ( )

USDIMAGING_API SdfPathVector UsdImagingStageSceneIndex::GetChildPrimPaths ( const SdfPath & primPath ) const

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. The traveral is expected to give exactly the set of paths where prim exists as defined in GetPrim. The traversal is also 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.

USDIMAGING_API HdSceneIndexPrim UsdImagingStageSceneIndex::GetPrim ( const SdfPath & primPath ) const

overridevirtual

Returns a pair of (prim type, datasource). A prim exists at primPath if and only if datasource is a non-null pointer. In particular, we consider the prim to exist even if the prim type or the container that datasource points to is empty.

Note that we require GetChildPrimPaths to be consistent with this notion of prim existence. That is, unless primPath is the absolute root path, the prim at primPath exists if and only if primPath is contained in GetChildPrimPaths of the parent path.

This function is expected to be threadsafe.

Implements HdSceneIndexBase.
