ObjectGeometryMesh

The ObjectGeometryMesh class provides mesh-based geometry support to ObjectGeometry. It defines rendered geometry by vertex and index offsets within ObjectMesh vertex and index buffers. The class supports multiple geometry batches that can be shaded by different Material references from ObjectGeometry. It also provides interfaces to set joint transformations and morph weights on associated NodeObjects.
