Class Triangulator

    java.lang.Object
      com.sun.j3d.utils.geometry.Triangulator

    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.

  `GeometryInfo`

Constructor Summary
`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 Summary
`void` | `triangulate(GeometryInfo gi)` This routine converts the GeometryInfo object from primitive type POLYGON_ARRAY to primitive type TRIANGLE_ARRAY using polygon decomposition techniques.

Constructor Detail

### Triangulator

    public 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.

  Creates a new instance of the Triangulator.

### Triangulator

    public 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.

  Creates a new instance of a Triangulator.

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
