Compatible tetrahedralizations
Marshall W. Bern · 1993
We give some special-case tetrahedralization algorithms. We first consider the problem of finding a tetrahedralization compatible with a fixed triangulation of the boundary of a polyhedron. We then adapt our solution to the related problem of compatibly tetrahedralizing the interior and exterior of a polyhedron. We also show how to tetrahedralize the region between nested convex polyhedra with O(n log n) tetrahedra and no Steiner points.
