USDIMAGING_API VtValue UsdImagingNurbsPatchAdapter::GetPoints ( UsdPrim const &  prim,
UsdTimeCode  time 
) const
overridevirtual

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 UsdImagingNurbsPatchAdapter::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.

overridevirtual

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

Reimplemented from UsdImagingGprimAdapter.

USDIMAGING_API bool UsdImagingNurbsPatchAdapter::IsSupported ( UsdImagingIndexProxy const *  index) const
overridevirtual

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

Reimplemented from UsdImagingPrimAdapter.

USDIMAGING_API SdfPath UsdImagingNurbsPatchAdapter::Populate ( UsdPrim const &  prim,
UsdImagingIndexProxy *  index,
UsdImagingInstancerContext const *  instancerContext = nullptr 
)
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.

Implements UsdImagingPrimAdapter.
