java.lang.OutOfMemoryError: Java heap space

[java3d-interest]

Hello All,

           I want to draw 4000 triangles. By using following Geometry array i have drawn all the triangles.

      TriangleArray landGeom = new TriangleArray(args.length, GeometryArray.COORDINATES|TriangleArray.COLOR_3);


But when i run sometimes iam getting a following exception


xception in thread "main" java.lang.OutOfMemoryError: Java heap space
       at javax.media.j3d.GeometryArrayRetained.createGeometryArrayData(Geo
ArrayRetained.java:1612)

       at Wrap3D.Tetrahedron(Viewer.java:178)
       at Wrap3D.createSceneGraph(Viewer.java:735)


How can i avoid this exception. Please help me

Thanking you.

Out of Memory Exceptions are solved quickly by using  -Xmx jvm option.
Example

java -Xmx256m MyApplication

But 4k triangles is a very simple geometry and should not raise an OEM exception for default -Xmx value of 64m, unless it is medium size swing application.
