For example in this picture :<a href="http://img684.imageshack.us/img684/6236/clipping.png">http://img684.imageshack.us/img684/6236/clipping.png</a> , The clip function is two vtkPlanes joined with a vtkImplicitBoolean. Until the two planes are distant enough, everything work as expected (see 1 and 2 on the picture). But when they are too close, i get some artefacts (3 and 4). The same thing happend with intersecting planes, near the intersections ( see <a href="http://img689.imageshack.us/img689/5623/boxclipcow.png">http://img689.imageshack.us/img689/5623/boxclipcow.png</a> , obtained with a vtkPlanes, from a vtkBoxWidget ). <br><br>Is this the right behaviour ? Is there any way
to obtain a clearly clipped polydata ?<br><br><br>The joined python script is derived from the clipcow vtk example and show this problem. To enable vtkImplicitPlaneWidget instead of a vtkBowWidget (like in the first picture) set use_boxWidget to False<br><br>--<br>Nicolas<br>
