Member Function Documentation

◆ Get()

USDIMAGING_API VtValue Get	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		TfToken const &	key,
		UsdTimeCode	time,
		VtIntArray *	outIndices
	)		const

overridevirtual

Gets the value of the parameter named key for the given prim (which has the given cache path) and given time.

If outIndices is not nullptr and the value has indices, it will return the unflattened value and set outIndices to the value's associated indices.

Reimplemented from UsdImagingPrimAdapter.

◆ GetCullStyle()

USDIMAGING_API HdCullStyle GetCullStyle	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time
	)		const

overridevirtual

Gets the cullstyle of a specific path in the scene graph.

Reimplemented from UsdImagingPrimAdapter.

◆ GetDoubleSided()

USDIMAGING_API bool GetDoubleSided	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time
	)		const

overridevirtual

Reads double-sided from the given prim. If not authored, returns false.

Reimplemented from UsdImagingPrimAdapter.

◆ GetExtent()

USDIMAGING_API GfRange3d GetExtent	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time
	)		const

overridevirtual

Reads the extent from the given prim.

If the extent is not authored, an empty GfRange3d is returned, the extent will not be computed.

Reimplemented from UsdImagingPrimAdapter.

◆ GetTopology()

USDIMAGING_API VtValue GetTopology	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time
	)		const

overridevirtual

Gets the topology object of a specific Usd prim.

If the adapter is a mesh it will return an HdMeshTopology, if it is of type basis curves, it will return an HdBasisCurvesTopology. If the adapter does not have a topology, it returns an empty VtValue.

Reimplemented from UsdImagingPrimAdapter.

◆ GetTransform()

USDIMAGING_API GfMatrix4d GetTransform	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time,
		bool	ignoreRootTransform = `false`
	)		const

overridevirtual

Fetches the transform for the given prim at the given time from a pre-computed cache of prim transforms.

Requesting transforms at incoherent times is currently inefficient.

Reimplemented from UsdImagingPrimAdapter.

◆ IsSupported()

bool IsSupported ( UsdImagingIndexProxy const * index ) const

overridevirtual

Returns true if the adapter can be populated into the target index.

Reimplemented from UsdImagingPrimAdapter.

◆ Populate()

SdfPath Populate	(	UsdPrim const &	prim,
		UsdImagingIndexProxy *	index,
		UsdImagingInstancerContext const *	instancerContext = `NULL`
	)

overridevirtual

Called to populate the RenderIndex for this UsdPrim.

The adapter is expected to create one or more Rprims in the render index using the given proxy.

Implements UsdImagingPrimAdapter.

◆ ProcessPrimRemoval()

USDIMAGING_API void ProcessPrimRemoval	(	SdfPath const &	cachePath,
		UsdImagingIndexProxy *	index
	)

overridevirtual

Removes all associated Rprims and dependencies from the render index without scheduling them for repopulation.

Reimplemented from UsdImagingPrimAdapter.

◆ ProcessPrimResync()

USDIMAGING_API void ProcessPrimResync	(	SdfPath const &	cachePath,
		UsdImagingIndexProxy *	index
	)

overridevirtual

When a PrimResync event occurs, the prim may have been deleted entirely, adapter plug-ins should override this method to free any per-prim state that was accumulated in the adapter.

Reimplemented from UsdImagingPrimAdapter.

◆ ProcessPropertyChange()

USDIMAGING_API HdDirtyBits ProcessPropertyChange	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		TfToken const &	propertyName
	)

overridevirtual

Returns a bit mask of attributes to be updated, or HdChangeTracker::AllDirty if the entire prim must be resynchronized.

Implements UsdImagingPrimAdapter.

◆ TrackVariability()

USDIMAGING_API void TrackVariability	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		HdDirtyBits *	timeVaryingBits,
		UsdImagingInstancerContext const *	instancerContext = `NULL`
	)		const

overridevirtual

For the given prim, variability is detected and stored in timeVaryingBits.

Initial values are cached into the value cache.

This method is expected to be called from multiple threads.

Implements UsdImagingPrimAdapter.

◆ UpdateForTime()

USDIMAGING_API void UpdateForTime	(	UsdPrim const &	prim,
		SdfPath const &	cachePath,
		UsdTimeCode	time,
		HdDirtyBits	requestedBits,
		UsdImagingInstancerContext const *	instancerContext = `NULL`
	)		const

overridevirtual

Populates the cache for the given prim, time and requestedBits.

This method is expected to be called from multiple threads.

Implements UsdImagingPrimAdapter.
