Hi Ali,<br>If you don't get answers to your questions, this is certainly because nobody has answers. They could be several reasons for that:<br>- your problem needs really high skills to be solved,<br>- you didn't explain your problem clearly enough,<br>
- people simply don't have time.<br><br>In my case, the second reason is why I *cannot* give you more helps. <br>But I guess that, for your first question, you want to use vtkMarchingCube to extract an isosurface from a volume. <br>
For your second question, your code doesn't make sense: you pass a triangulated mesh through a vtkDelaunay3D filter, that is a triangulation process... Despite this, I tried to apply delaunay on a sphere source in paraview, and I effectively get "Unable to factor linear system" as VTK warning (not error). But I get an almost valid output (2 degenerate triangles are encountered). If you try to triangulate the output of vtkPointSource (produces a point cloud), you will find a nice triangulation of the points that are on the bounding surface.<br>
<br>And once again, please do not send private message, since I am just a vtk-user like the other people that subscribe to the list.<br><br>Best regards,<br>Jerome<br><br><div class="gmail_quote">2009/10/19 Ali Habib <span dir="ltr"><<a href="mailto:ali.mahmoud.habib@gmail.com" target="_blank">ali.mahmoud.habib@gmail.com</a>></span><br>
