Thanks so much for your time. 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.
