Detailed Description

A scene index that observes an input scene index and produces a comparable scene in which inherited state is represented at leaf prims.

This kind of representation is typically required for legacy-style render delegates that require all the information to be available at the leaf prims.

void HdFlatteningSceneIndex::_PrimsAdded	(	const HdSceneIndexBase &	sender,
		const HdSceneIndexObserver::AddedPrimEntries &	entries
	)

Implements HdSingleInputFilteringSceneIndexBase.

void HdFlatteningSceneIndex::_PrimsDirtied	(	const HdSceneIndexBase &	sender,
		const HdSceneIndexObserver::DirtiedPrimEntries &	entries
	)

overrideprotectedvirtual

Implements HdSingleInputFilteringSceneIndexBase.

void HdFlatteningSceneIndex::_PrimsRemoved	(	const HdSceneIndexBase &	sender,
		const HdSceneIndexObserver::RemovedPrimEntries &	entries
	)

overrideprotectedvirtual

Implements HdSingleInputFilteringSceneIndexBase.

HD_API SdfPathVector HdFlatteningSceneIndex::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.

const TfTokenVector& HdFlatteningSceneIndex::GetFlattenedDataSourceNames ( ) const

inline

Data sources under locator name in a prim source get flattened.

Definition at line 87 of file flatteningSceneIndex.h.

const HdFlattenedDataSourceProviderSharedPtrVector& HdFlatteningSceneIndex::GetFlattenedDataSourceProviders ( ) const

inline

Providers in the same order as GetFlattenedDataSourceNames.

Definition at line 93 of file flatteningSceneIndex.h.

HD_API HdSceneIndexPrim HdFlatteningSceneIndex::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.

static HdFlatteningSceneIndexRefPtr HdFlatteningSceneIndex::New	(	HdSceneIndexBaseRefPtr const &	inputScene,
		HdContainerDataSourceHandle const &	inputArgs
	)

inlinestatic

Creates a new flattening scene index. inputArgs maps names to HdFlattenedDataSourceProviderSharedPtr's. That provider flattens the data sources under the locator name in each prim source.
