Class Triangulator

java.lang.Object

org.scijava.java3d.utils.geometry.Triangulator

public class Triangulator
extends 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.

Constructor and Description
Triangulator() Deprecated. This class is created automatically when needed in GeometryInfo and never needs to be used directly. Putting data into a GeometryInfo with primitive POLYGON_ARRAY automatically causes the triangulator to be created and used.
Triangulator(int earOrder) Deprecated. This class is created automatically when needed in GeometryInfo and never needs to be used directly. Putting data into a GeometryInfo with primitive POLYGON_ARRAY automatically causes the triangulator to be created and used.

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
