public class Triangulator
extends java.lang.Object

Triangulator is a utility for turning arbitrary polygons into triangles so they can be rendered by Java 3D. Polygons can be concave, nonplanar, and can contain holes.

Method Detail

triangulate

public void triangulate(GeometryInfo gi)

This routine converts the GeometryInfo object from primitive type POLYGON_ARRAY to primitive type TRIANGLE_ARRAY using polygon decomposition techniques.

 Example of usage:
   Triangulator tr = new Triangulator();
   tr.triangulate(ginfo); // ginfo contains the geometry.
   shape.setGeometry(ginfo.getGeometryArray()); // shape is a Shape3D.

Parameters:

gi - Geometry to be triangulated
