virtual

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.

Reimplemented in UsdImagingGLDrawModeAdapter.

USDIMAGING_API TfToken UsdImagingPrimAdapter::GetInheritablePurpose

(

UsdPrim const &

prim

)

const

Returns the purpose token for prim, but only if it is inheritable by child prims (i.e. it is an explicitly authored purpose on the prim itself or one of the prim's ancestors), otherwise it returns the empty token.

virtual USDIMAGING_API std::vector<VtArray<TfToken> > UsdImagingPrimAdapter::GetInstanceCategories ( UsdPrim const &  prim )

virtual

Return an array of the categories used by each instance.

Reimplemented in UsdImagingInstanceAdapter.

USDIMAGING_API SdfPath UsdImagingPrimAdapter::GetMaterialUsdPath

const

Gets the material path for the given prim, walking up namespace if necessary.

USDIMAGING_API TfToken UsdImagingPrimAdapter::GetModelDrawMode

(

UsdPrim const &

)

Gets the model:drawMode attribute for the given prim, walking up the namespace if necessary.

USDIMAGING_API VtArray<VtIntArray> UsdImagingPrimAdapter::GetPerPrototypeIndices	(	UsdPrim const &	prim,
		UsdTimeCode	time
	)		const

Computes the per-prototype instance indices for a UsdGeomPointInstancer. XXX: This needs to be defined on the base class, to have access to the delegate, but it's a clear violation of abstraction. This call is only legal for prims of type UsdGeomPointInstancer; in other cases, the returned array will be empty and the computation will issue errors.

USDIMAGING_API TfToken UsdImagingPrimAdapter::GetPurpose	(	UsdPrim const &	prim,
		UsdImagingInstancerContext const *	instancerContext
	)		const

Returns the purpose token for prim. If an instancerContext is provided and the prim doesn't have an explicitly authored or inherited purpose, it may inherit the instancerContext's purpose if the instance has an explicit purpose.

virtual USDIMAGING_API GfMatrix4d UsdImagingPrimAdapter::GetRelativeInstancerTransform ( SdfPath const &  instancerPath, SdfPath const &  protoInstancerPath, UsdTimeCode  time  ) const

virtual

Returns the transform of protoInstancerPath relative to instancerPath. instancerPath must be managed by this adapter.

Reimplemented in UsdImagingInstanceAdapter, and UsdImagingPointInstancerAdapter.

USDIMAGING_API GfMatrix4d UsdImagingPrimAdapter::GetRootTransform

(

)

const

The root transform provided by the delegate.

Reimplemented in UsdImagingInstanceAdapter, and UsdImagingPointInstancerAdapter.

virtual USDIMAGING_API PxOsdSubdivTags UsdImagingPrimAdapter::GetSubdivTags ( UsdPrim const &  usdPrim, SdfPath const &  cachePath, UsdTimeCode  time  ) const

virtual

USDIMAGING_API GfMatrix4d UsdImagingPrimAdapter::GetTransform	(	UsdPrim const &	prim,
		UsdTimeCode	time,
		bool	ignoreRootTransform = false
	)		const

Fetches the transform for the given prim at the given time from a pre-computed cache of prim transforms. Requesting transforms at incoherent times is currently inefficient.

USDIMAGING_API bool UsdImagingPrimAdapter::GetVisible	(	UsdPrim const &	prim,
		UsdTimeCode	time
	)		const

Returns true if the given prim is visible, taking into account inherited visibility values. Inherited values are strongest, Usd has no notion of "super vis/invis".

SdfPath const &

path

const

The root transform provided by the delegate.

virtual USDIMAGING_API bool UsdImagingPrimAdapter::IsInstancerAdapter ( ) const

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.

Reimplemented in UsdImagingPointInstancerAdapter, and UsdImagingInstanceAdapter.

virtual bool UsdImagingPrimAdapter::IsSupported ( UsdImagingIndexProxy const *  index ) const
