public class IndexedTriangleFanArray
extends IndexedGeometryArray
implements org.openmali.spatial.WriteableTriangleContainer

(Indexed)TriangleFanArray defines a triangle array, where the first vertex is part of any triangle. The second and thirtvertex form the first triangle (together with the first vertex) and the fourth and fifth triangle form the second triangle (together with the first vertex) and so forth.

In the Indexed version the first vertex is the one referenced by the number in the first element of the index array.
