POLTHIER K.: Parameterizing singularities of positive integral index
Classical surface parameterization algorithms often place singular-ities in order to enhance the quality of the resulting parameter map. Unfortunately, singularities of positive integral index (as the north pole of a sphere) were not handled since they cannot be described with piecewise linear param...
