Detailed Description

HdLegacyGeomSubsetSceneIndex

This scene index converts legacy geom subsets (from mesh or basis curves topology, including invisible components) into Hydra geomSubset prims. It preserves the authored order of named mesh subsets as USD requires. It MUST have a notice-batching scene index before it so that it can access topology via the scene delegate during insertion.

For the most part, this scene index will pull information from the scene delegate on demand. However, it does keep a cache of all the subset paths it has added (organized by parent) so it can be more precise about invalidation. Having this cache incidentally provides a few other shortcuts to avoid expensive operations.

HD_API SdfPathVector HdLegacyGeomSubsetSceneIndex::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.

HD_API HdSceneIndexPrim HdLegacyGeomSubsetSceneIndex::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.
