One of the achievements of Shewchuk's Delaunay procedure, besides the
triangulation, is the exact arithmetic for floating point operations. Which
is of great
importance in the context of finite element simulations.
Before his release of the pyramid algorithm, there is also tetgen, that
claims to be
a "A Quality Tetrahedral Mesh Generator and Three-Dimensional Delaunay
