Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

RE: 3D Visualization Problem

Please excuse my ignorance in visad,I used the DelaunayCuston(flooat[][] samlple, int[][] tri) to generate Delaunay Triangulationa and tested to be right (return true with Delaunay.test(samples)). Then I passes it to Irregular3DSet to establish the domain set. Why still it just give me some points in 3d space instead of 3d graph? Do I have to use the complete DelaunayCustom Constructor?If anyone could please attach me a short program on using Irregular3DSet, see to visualizing a cube but the samples are irregular, I will appreciate it very much. Thanks so much for your time. 

regards.

Yi
