USDIMAGING_API void UsdImagingSelectionSceneIndex::AddSelection | ( | const SdfPath & | usdPath | ) |
Given a path (including usd proxy path inside a native instance) of a USD prim, determine the corresponding prim in the Usd scene index (filtered by the UsdImagingNiPrototypePropagatingSceneIndex) and populate its selections data source.
USDIMAGING_API void UsdImagingSelectionSceneIndex::ClearSelection | ( | ) |
Reset the scene index selection state.

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 |
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.
