public class Polygon

extends Shape

implements Serializable, Cloneable

This class represents a polygon (graphic object, leaf). A polygon includes coordinates, normals, textureCoordinates and a bounding box. For a wire frame visualization only the coordinates are needed. For a solid visualization the coordinates and the normals are needed. For a textured visualization the coordinates, the normals and the textureCoordinates are needed. The bounding box is stored permanently. Title : Earth Copyright : Copyright (c) 2001 Organisation : IGD FhG
