SoFaceSet
The SoFaceSet class is used to render and organize non-indexed polygonal face data.Faces are specified using the numVertices field. Coordinates, normals, materials and texture coordinates are fetched in order from the current state or from the vertexProperty node if set. For example, if numVertices is set to [3, 4, 5, 3], this node would specify a triangle from coordinates 0, 1 and 2, a quad from coordinates 3, 4, 5 and 6, a polygon from coordinates 7, 8, 9, 10 and 11 and finally a triangle from coordinates 12, 13, 14.
