[vtkusers] meshing of polydata

[WolfgangZ]

Hi all,

I have some polydata with around 100 Polygons which describe some 
objects. All polys are closed objects. Now I want to crate a triangle 
mesh with these lines (the lines describe the border between two 
materials) and I want to use that mesh in a finite element analysis. I 
tried vtkDelaunay2D but the resulting mesh has only points on the 
original polygon and therefore most triangles have sharp edges.
Is there a better way to mesh my geometry?

I already found the SubdivionFilters but these divide all cells and many 
cells are getting too small. I would prefer a method that directly gives 
me a triangles with roughly the same edge length.

Any comments if this is possible with vtk at all?

Regards
Wolfgang
