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.

◆ GetTopology()

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.

◆ IsSupported()

USDIMAGING_API bool IsSupported ( UsdImagingIndexProxy const *  index) const
overridevirtual

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

Reimplemented from UsdImagingPrimAdapter.

◆ Populate()

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.

◆ ProcessPropertyChange()

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.

Reimplemented from UsdImagingGprimAdapter.

◆ TrackVariability()

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

Thread Safe.

Reimplemented from UsdImagingGprimAdapter.
