Volume Meshing for Polyhedra

Standard Delaunay refinement works only for polyhedra with input angles no more than 90 degrees. It was a challenge to extend it to polyhedra with small input angles. Recently we designed an algorithm to handle polyhedra with small input angles in the following paper. S. W. Cheng, T. K. Dey, E. A. Ramos and T. Ray. Quality meshing for polyhedra with small angles.
