Triangulation of a polygonal surface
Posted:
Dec 25, 2012 6:04 AM


Dear participants of the MATLAB forum,
I would like to develop a Finite Element application for 2D problems in MATLAB. Having the parametric representation of a 2D surface, the first difficulty I am facing is to make a triangulation out of it. I can compute points on the surface boundary and thus obtain a polygonal approximation of the boundary.
Is there any way that I can optimally mesh this surface with triangles?
I tried the Delaunay algorithm but for this I need points in the interior of the surface which I do not know how to optimally distribute. Is there any way that one can optimally distribute points on a parametric surface X=X(u,v) ? Moreover the surface can be convex or concave.
Thanks in advance for your help,
Best Regards, Andreas
