Member Function Documentation

USDIMAGING_API bool IsSupported ( UsdImagingIndexProxy const *  index) const
overridevirtual

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

Reimplemented from UsdImagingPrimAdapter.

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 
)
overridevirtual

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

Implements UsdImagingPrimAdapter.
