- Direct Known Subclasses:
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.

public IFS(Vector3D vertexList, int faceData)Create a polyhedron, using specifed lists of vertices and faces. The data is not verified.
vertexList- an array containing the vertices of the polyhedron
faceData- describes the faces of the polyhedron. faceData[i] is a list of vertices in the i-th face, listed in counterclockwise order as seen from in front of the face, with each vertex specified as an index into the vertex array.
public View getDefaultView()Returns a View of type
getCreateAnimationReturns an animation in which the faces of the polyhedron are drawn one at a time, in back-to-front order.
view- A View that is displaying this Exhibit. The animation, if any, that is returned by this method will be installed in the View's display. If the view is null, than a creation animation that can run independently of a view could be returned.
- A creation animation for the given View of this Exhibit. The return value can be null to indicate that no creation animation is to be run.
