USDIMAGING_API TfTokenVector const& UsdImagingBasisCurvesAdapter::_GetRprimPrimvarNames ( ) const

overrideprotectedvirtual

Returns the primvar names known to be supported for the rprims this adapter produces. These primvar names are excepted from primvar filtering.

Reimplemented from UsdImagingGprimAdapter.

USDIMAGING_API bool UsdImagingBasisCurvesAdapter::_IsBuiltinPrimvar ( TfToken const & primvarName ) const

overrideprotectedvirtual

Give derived classes an opportunity to override how we get points for a prim. This is useful for implicit primitives.

Reimplemented from UsdImagingGprimAdapter.

USDIMAGING_API VtValue UsdImagingBasisCurvesAdapter::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.

USDIMAGING_API HdContainerDataSourceHandle UsdImagingBasisCurvesAdapter::GetImagingSubprimData	(	UsdPrim const &	prim,
		TfToken const &	subprim,
		const UsdImagingDataSourceStageGlobals &	stageGlobals
	)

overridevirtual

Returns the prim's behavior with regard to population and invalidation. See PopulationMode for possible values.

Reimplemented from UsdImagingPrimAdapter.

USDIMAGING_API TfTokenVector UsdImagingBasisCurvesAdapter::GetImagingSubprims ( UsdPrim const & prim )

overridevirtual

Returns the prim's behavior with regard to population and invalidation. See PopulationMode for possible values.

Reimplemented from UsdImagingPrimAdapter.

USDIMAGING_API TfToken UsdImagingBasisCurvesAdapter::GetImagingSubprimType	(	UsdPrim const &	prim,

USDIMAGING_API VtValue UsdImagingBasisCurvesAdapter::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.

		TfToken const &	subprim,
		TfTokenVector const &	properties,

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

Reimplemented from UsdImagingPrimAdapter.

overridevirtual

Called to populate the RenderIndex for this UsdPrim. The adapter is expected to create one or more prims in the render index using the given proxy.
