Detailed Description

A scene index that prunes materials and material bindings.

The scene index can be disabled.

If enabled, prims of type material are pruned unless the bool data source at a specified locator return true. The locator can be specified by giving a builtinMaterialLocator to the inputArgs when constructing the scene index.

Furthermore, for a prim that is not a material, the materialBindings are pruned unless the bool data source for materialIsFinal of the HdLegacyDisplayStyleSchema returns true.

Note that an alternative implementation could prune a material if the all materialBindings targeting the material have been pruned. However, we chose here to go for a simpler implementation and require clients to tag materials as builtin.

overrideprotectedvirtual
HDSI_API SdfPathVector HdsiSceneMaterialPruningSceneIndex::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.

HDSI_API bool HdsiSceneMaterialPruningSceneIndex::GetEnabled ( ) const

Is scene index actually pruning?

HDSI_API HdSceneIndexPrim HdsiSceneMaterialPruningSceneIndex::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.
