Detailed Description

A scene index replacing geometry based on the draw mode.

Inspects a prim's values for drawMode and applyDrawMode (see UsdImagingGeomModelSchema). If the drawMode is valid and not the default and applyDrawMode is true, the prim and all its descendents are replaced by stand-in geometry specified by the draw mode.

Note that the material that ensures the correct texture is used on each face is using glslfx nodes and thus only works properly in Storm.

Using a UsdPreviewSurface instead (so that it works accross different renderers) probably requires breaking up the geometry into several pieces.

USDIMAGING_API SdfPathVector UsdImagingDrawModeSceneIndex::GetChildPrimPaths ( const SdfPath primPath) const
overridevirtual

Returns the paths of all scene index prims located immediately below primPath. This function can be used to traverse the scene by recursing from SdfPath::AbsoluteRootPath(); such a traversal is expected to give the same set of prims as the flattening of the scene index's PrimsAdded and PrimsRemoved messages. This function is expected to be threadsafe.

Implements HdSceneIndexBase.

USDIMAGING_API HdSceneIndexPrim UsdImagingDrawModeSceneIndex::GetPrim ( const SdfPath primPath) const
overridevirtual

Returns a pair of (prim type, datasource) for the object at primPath. If no such object exists, the type will be the empty token and the datasource will be null. This function is expected to be threadsafe.

Implements HdSceneIndexBase.

static USDIMAGING_API UsdImagingDrawModeSceneIndexRefPtr UsdImagingDrawModeSceneIndex::New ( const HdSceneIndexBaseRefPtr &  inputSceneIndex,
const HdContainerDataSourceHandle &  inputArgs 
)
static

inputArgs unused for now. In the future, we might use it to say that we want to break up the geometry and use UsdPreviewSurface to work across different renderers.
