This property determines how the sequence of indices in the submesh’s index buffer should be interpreted for rendering. For example, if the geometry type is
MDLGeometry, each triangle to be rendered comes from an independent set of three indices, but if the geometry type is
MDLGeometry, triangles to be rendered can come from overlapping sets of indices in the sequence. If the geometry type is
topology property describes the non-uniform layout of the index buffer.
