Detailed Description

UsdImagingRerootingSceneIndex.

Drops all prims not under srcPrefix and moves those under srcPrefix to dstPrefix.

Data sources containing paths will be updated accordingly. That is, if it contains a path with srcPrefix as prefix, the prefix will be replaced by dstPrefix.

Note that this can be used as prefixing scene index by setting srcPrefix to the root path. It can also use to isolate part of the namespace by setting the srcPrefix and dstPrefix to be equal.

Member Function Documentation

◆ GetChildPrimPaths()

USDIMAGING_API SdfPathVector 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(); 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.

◆ GetPrim()

USDIMAGING_API HdSceneIndexPrim GetPrim ( const SdfPath & primPath ) const

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.
