If you still get points, that probably means that your
Irregular3DSet has manifold dimension = 3. Your 'int[][] tri'
should be dimensioned int[ntris][3] to define 2-D triangles,
rather than int[ntris][4] which would define 3-D tetrahedra.
You should have to use the complete DelaunayCustom Constructor.
I think it is only a matter of manifold dimension.
Good luck,
Bill
