triangles in Irregular3DSet

Hi All,

I am wondering how I can generate a wire frame shape composed of the triangles (DelaunayCustom(samples,tri)) from the Irregular3DSet. In other words, instead of a surface with "skin" I would like to see the skeletons or the triangles that make up the surface.

I know for Gridded3DSet I can achieve this with for example the following code:

Gridded3DSet testset = new Gridded3DSet(xyz,testsamples,testsamples[0].length);
        DataReferenceImpl wire_ref = new DataReferenceImpl("points_ref");
        wire_ref.setData((Set)testset);

        ConstantMap[] pointsCMap = { new ConstantMap( 1.0f, Display.Red ),
                             new ConstantMap( 0.0f, Display.Green ),
                             new ConstantMap( 0.0f, Display.Blue ),
                             new ConstantMap( 5.50f, Display.PointSize )  };

        display.addReference( wire_ref, pointsCMap );

Is there a way to see the triangles for Irregular3DSet?

thanks very much,
john
