Right now I've got a python module that can render a point cloud with 2.5m elements. What I'd like to do is add functionality to have per-point colors, per-point sizes, and a per-point selector so I can execute code based on which point is selected. I have searched the mailing list and the one thread about VTKPointCloud didn't seem to address the first two questions. Is it possible to do this in VTK?</div><div><br></div><div>Thanks!<span class="HOEnZb"><font color="#888888"><br>Tudor</font></span></div></div>
