<br>Hi Sebastien,<br><br>You could avoid this problem by simply<br>using the QuadEdgeMesh class.<br><br><a href="http://www.itk.org/Doxygen/html/classitk_1_1QuadEdgeMesh.html">http://www.itk.org/Doxygen/html/classitk_1_1QuadEdgeMesh.html</a><br>
<br>The structure of the QuadEdgeMesh class<br>is designed from the base to ensure the<br>consistency of the orientation of its cells.<br><br><br> Luis<br><br><br>---------------------------------------------------<br>

<br>
i wrote a few days ago, that some Normals of my SimplexMesh are flipped and i still have no clue why. I used the ComputeNormal function of itk::SimplexMesh and i calculated it 2 times myself like written in delingette'99 and the standard way with cross-produkt.<br>
<br>
<br>
Apart from that i have another question. When i use a model as inital mesh for deformation, then the surface has some parts where it is slightly concave. My Problem here is, that when i deform the surface along the normals, it can happen that the surface self-intersects at these parts. Is the an opportunity to solve this problem? A Class that detects self-intersections or that can decimate the SimplexMesh? Or anything in literature to solve this problem, i didn't found something interesting yet.<br>
When i decimate the triangulated SimplexMesh in vtk via decimatePro or QuadricDecimation, it doesent solve the problem and the mesh looks inordinate in relation to the size of the cells.<br>
