Maybe vtkTriangleFilter should clear degenrate triangles .<br><br><div class="gmail_quote">On Mon, Oct 11, 2010 at 7:28 AM, Eduardo Suarez-Santana <span dir="ltr"><<a href="mailto:esuarez@itccanarias.org">esuarez@itccanarias.org</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> I'm using a vtkMarchingCubes and a vtkTriangleFilter to get a<br>
triangular mesh from a 3-d image dataset.<br>
<br>
However, I get a triangular mesh with some extra-triangles on it. That<br>
is, I get a triangle sharing one edge (let's say edge X) with the mesh,<br>
and with its opposite vertex just belonging to this triangle. In other<br>
words, edge X belongs to three triangles, two from the correct mesh, one<br>
from an extra triangle.<br>
<br>
Is there a way to avoid the creation of these triangles, or to remove<br>
them? I tried vtkFeatureEdges with no success.<br>
<br>
Thanks,<br>
