USDIMAGING_API VtValue 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 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.

USDIMAGING_API bool IsSupported ( UsdImagingIndexProxy const *  index ) const

overridevirtual

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

Reimplemented from UsdImagingPrimAdapter.

USDIMAGING_API SdfPath 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.

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

virtual

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

Reimplemented from UsdImagingGprimAdapter.

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

overridevirtual

Thread Safe.

Implements UsdImagingPrimAdapter.
