“Isosurface stuffing improved: acute lattices and feature matching” by Doran, Chang and Bridson

Tetrahedral mesh generation is an important tool in graphics, both for discretizing dynamics in animation and in providing a domain for geometric algorithms. The search for faster methods which produce higher quality tetrahedra continues. Here we present two modifications of Labelle and Shewchuk’s isosurface stuffing [2007], which is exceptionally fast, provides good quality tetrahedra (with strong bounds), and has a simple implementation — with the caveat it only applies to smooth geometry.
