I have not been able to find a good way to do this. I've heard that you can use a 3d delaunay triangulation (which fills a volume with tetrahedrons) and then take the outer surface, but I haven't had any success with that. Here is an example that generates random points on a sphere and produces the surface through those points. I'm not sure what these filters do under the hood, but it seems to work well with this simple data set. <br>
<br>Good luck - let us know the results.<br><br clear="all">Thanks,<br><br>David<br>
