Detailed Description

If prim P has a coord sys binding FOO to another prim Q, the scene index will add a coord sys prim Q.__coordSys:FOO under Q. It will rewrite the coord sys binding on P to point to Q.__coordSys:FOO and use Q's xform data source for Q.__coordSys:FOO.

Motivation: USD allows for a coord sys binding to target any xformable prim. Some render delegates, however, only allow a coord sys binding to point to a prim of type coord sys. This scene index is creating prim's of that type for such render delegates.

For compatibility with the UsdImagingDelegate which is already adding a coord sys prim under Q itself using a property path, we ignore coord sys bindings to paths which are not prim paths.

An example:

Input to scene index:

/MyXform dataSource: xform: [ some xform ] /MyPrim dataSource: coordSysBinding: FOO: /MyXform

Will be transformed to:

/MyXform dataSource: xform: [ some xform ] /MyXform.__coordSys:FOO dataSource: coordSys: name: FOO xform: [ as above ] /MyPrim dataSource: coordSysBinding: FOO: /MyXform.__coordSys:FOO

HDSI_API SdfPathVector HdsiCoordSysPrimSceneIndex::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.

HDSI_API HdSceneIndexPrim HdsiCoordSysPrimSceneIndex::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 HdsiCoordSysPrimSceneIndexRefPtr HdsiCoordSysPrimSceneIndex::New ( HdSceneIndexBaseRefPtr const & inputScene )

Creates a new coord sys prim scene index.
