public class Star
extends TriMesh

Star defines a N-sided, two dimensional star. The star fits in a circle with diameter size units. The center is at the origin. Texture coordinates are assigned such that i ranges from 0 at the center of the star to 1/2 where the points meet, to 1 at the tip of the point; and j ranges from 0 at the centerline of the point, to 1 at the edge of the point. This texture assignment makes it easy to create textures with radial gradients or outlines, but probably makes it hard to overlay an undistorted image on the star.
