Dear mailing list members,<br>
<br>
<br>
Recently, I came across a voxel-dataset that when meshed with vtkMarchingCubes results in a mesh that contains non-manifold edges (magenta line in attached image).<br>
How can this be avoided?<br>
Using paraview's contour filter and switching off "Generate Triangles" creates a slightly different surface mesh that does not contain non-manifold edges. However vtkMarchingCubes does not seem to have any option concerning triangulation.<br>
What filter/option do I have to use to get the same result just with pure VTK?<br>
<br>
As a workaround: Is it possible to split the mesh at non-manifold edges? vtkIntersectionPolyDataFilter sounds promising but seems to need surfaces not just the edges.<br>
<br>
Any help or hints are very much appreciated<span class="HOEnZb"><font color="#888888"><br>
