Detailed Description

Delegate support for UsdGeomHermiteCurves.

As Hydra doesn't support imaging of Hermite curves, we render the points as linearly interpolated BasisCurves, ignoring tangents, widths, and normals.

Member Function Documentation

USDIMAGING_API bool UsdImagingHermiteCurvesAdapter::_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 UsdImagingHermiteCurvesAdapter::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 UsdImagingHermiteCurvesAdapter::IsSupported ( UsdImagingIndexProxy const *  index) const
overridevirtual

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

Reimplemented from UsdImagingPrimAdapter.

USDIMAGING_API SdfPath UsdImagingHermiteCurvesAdapter::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 UsdImagingHermiteCurvesAdapter::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.

Reimplemented from UsdImagingGprimAdapter.

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

Thread Safe.

Reimplemented from UsdImagingGprimAdapter.
