Dear CGAL experts, 

my student Shrabani Ghosh has been using the Triangulated Surface Mesh Simplification algorithm, in attempting to decimate a surface model of the human cranium. This model makes explicit the cranial openings, or foramina, and we are adopting a decimation strategy where the foramina faces are held as constant. My question to the community is: how can we ensure that the surface mesh produces compact triangular faces? If I look at what our results look like, and compare that to the three hand models on the website, the hand models have exquisite compact triangles everywhere, while our results have a number of elongated faces. Is this a parameter in the simplification that we can set, in order to make the decimation define new faces with low aspect ratios? 

Thanks for your kind support. Best wishes,

Michel
