public class IFSextends Exhibit3DRepresents a polyhedron given in the form of a indexed face set. That is, the data for the polyhedron consists of a list of vertices plus a list of data for the faces of the polyhedron. A face is specified by a list of integers, one for each vertex of the face, where each integer is an index into the list of vertices. The vertices for a face must be listed in counterclockwise order as viewed from the front of face. No public method is provided for changing the indexed face set data after the object is constructed, but subclasses can do so using the protected method
An IFS has a create animation that shows the faces of the polyhedron being drawn in back-to-front order using a simple painter's algorithm.
