This node creates geometry from a indexed reference list of vertices. The index list uses a sentinel value of -1 to indicate the end of a face. It is not necessary to include the initial vertex as the ending vertex as each face must be closed. The algorithm for rendering this shape triangulates each face as a triangle fan with the initial defined vertex for the face being the common vertex of the fan.
