Detailed Description

Scene delegate which observes notices from an HdSceneIndex and applies them to an HdRenderIndex. This serves as "back-end" emulation in order for scenes described via the HdSceneIndex/HdDataSource APIs to be accessible by legacy render delegates.

SdfPath HdSceneIndexAdapterSceneDelegate::GetDataSharingId ( SdfPath const & primId )

overridevirtual

Returns an identifier that can be used to share data between HdPrims during a Sync operation. Any number of HdPrims of the same type may return the same identifier. In this situation, the render delegate can choose to share information between HdPrims rather than fetching data for each HdPrim. For the UsdImagingSceneDelegate, this identifier will be the path of the GetPrototype prim for the UsdPrim correspnding to this HdPrim. Returns an empty SdfPath if this feature is no supported or the UsdPrim has no prototype. Render delegates are free to ignore this method completely if they aren't interested in the additional level of data sharing enabled by this information.

Reimplemented from HdSceneDelegate.

overridevirtual

Returns the refinement level for the given prim in the range [0,8].

		HdExtComputationContext *	context
	)

overridevirtual

Requests the scene delegate run the ExtComputation with the given id. The context contains the input values that delegate requested through GetExtComputationInputNames().

The scene delegate is expected to set each output identified by GetExtComputationOutputNames() on the context.

Hydra may invoke the computation on a different thread from what HdEngine::Execute() was called on. It may also invoke many computations in parallel.

Reimplemented from HdSceneDelegate.

Reimplemented from HdSceneDelegate.

void HdSceneIndexAdapterSceneDelegate::PrimsAdded	(	const HdSceneIndexBase &	sender,
		const AddedPrimEntries &	entries
	)

overridevirtual

A notification indicating prims have been added to the scene. The set of scene prims compiled from added/removed notices should match the set from a traversal based on sender.GetChildPrimNames. Each prim has a path and type. It's possible for PrimsAdded to be called for prims that already exist; in that case, observers should be sure to update the prim type, in case it changed, and resync the prim. This function is not expected to be threadsafe.

Implements HdSceneIndexObserver.

void HdSceneIndexAdapterSceneDelegate::PrimsDirtied	(	const HdSceneIndexBase &	sender,
		const DirtiedPrimEntries &	entries
	)

overridevirtual

A notification indicating prim datasources have been invalidated. This message is not considered hierarchical on primPath; if /Path is dirtied, /Path/child is not necessarily dirtied. However datasource locators are considered hierarchical: if primvars is dirtied on a prim, primvars/color is considered dirtied as well. This function is not expected to be threadsafe.

Implements HdSceneIndexObserver.

void HdSceneIndexAdapterSceneDelegate::PrimsRemoved	(	const HdSceneIndexBase &	sender,
		const RemovedPrimEntries &	entries
	)

overridevirtual

A notification indicating prims have been removed from the scene. Note that this message is considered hierarchical; if /Path is removed, /Path/child is considered removed as well. This function is not expected to be threadsafe.

Implements HdSceneIndexObserver.

void HdSceneIndexAdapterSceneDelegate::PrimsRenamed	(	const HdSceneIndexBase &	sender,
		const RenamedPrimEntries &	entries
	)

overridevirtual

A notification indicating prims (and their descendants) have been renamed or reparented. This function is not expected to be threadsafe.

Implements HdSceneIndexObserver.

size_t HdSceneIndexAdapterSceneDelegate::SampleExtComputationInput	(	SdfPath const &	computationId,
		TfToken const &	input,
		size_t	maxSampleCount,
		float *	sampleTimes,
		VtValue *	sampleValues
	)

overridevirtual

Return up to maxSampleCount samples for a given computation id and input token. The token may be a computation input or a computation config parameter. Returns the union of the authored samples and the boundaries of the current camera shutter interval. If this number is greater than maxSampleCount, you might want to call this function again to get all the authored data.

Reimplemented from HdSceneDelegate.

size_t HdSceneIndexAdapterSceneDelegate::SampleIndexedPrimvar	(	SdfPath const &	id,
		TfToken const &	key,
		size_t	maxSampleCount,
		float *	sampleTimes,
		VtValue *	sampleValues,
		VtIntArray *	sampleIndices
	)

overridevirtual

SamplePrimvar() for getting an unflattened primvar and its indices. If *sampleIndices is not nullptr and the primvar has indices, it will return unflattened primvar samples in *sampleValues and the primvar's sampled indices in *sampleIndices, clearing the *sampleIndices array if the primvar is not indexed.

Reimplemented from HdSceneDelegate.

size_t HdSceneIndexAdapterSceneDelegate::SampleInstancerTransform	(	SdfPath const &	instancerId,
		size_t	maxSampleCount,
		float *	sampleTimes,
		GfMatrix4d *	sampleValues
	)

overridevirtual

Store up to maxSampleCount transform samples in *sampleValues. Returns the union of the authored samples and the boundaries of the current camera shutter interval. If this number is greater than maxSampleCount, you might want to call this function again to get all the authored data. Sample times are relative to the scene delegate's current time.

See Also: GetInstancerTransform()

Reimplemented from HdSceneDelegate.

size_t HdSceneIndexAdapterSceneDelegate::SamplePrimvar	(	SdfPath const &	id,
		TfToken const &	key,
		size_t	maxSampleCount,
		float *	sampleTimes,
		VtValue *	sampleValues
	)

overridevirtual

Store up to maxSampleCount primvar samples in *samplesValues. Returns the union of the authored samples and the boundaries of the current camera shutter interval. If this number is greater than maxSampleCount, you might want to call this function again to get all the authored data.

Sample values that are array-valued will have a size described by the HdPrimvarDescriptor as applied to the toplogy.

For example, this means that a mesh that is fracturing over time will return samples with the same number of points; the number of points will change as the scene delegate is resynchronized to represent the scene at a time with different topology.

Sample times are relative to the scene delegate's current time.

Reimplemented from HdSceneDelegate.

size_t HdSceneIndexAdapterSceneDelegate::SampleTransform	(	SdfPath const &	id,
		size_t	maxSampleCount,
		float *	sampleTimes,
		GfMatrix4d *	sampleValues
	)

overridevirtual

Store up to maxSampleCount transform samples in *sampleValues. Returns the union of the authored samples and the boundaries of the current camera shutter interval. If this number is greater than maxSampleCount, you might want to call this function again to get all the authored data. Sample times are relative to the scene delegate's current time.
