  author={Neil Molino and Robert Bridson and Ronald Fedkiw},
Motivated by the simulation of deformable bodies, we propose a new tetrahedral mesh generation algorithm that produces both high quality elementsanda mesh that is well conditioned for subsequent large deformations. We use a signed distance function defined on a grid in order to represent the object geometry. After tiling space with a uniform lattice based on crystallography, we identify a subset of these tetrahedra that adequately fill the space occupied by the object. Then we use the signed… CONTINUE READING
