Cardinality Bounds for Triangulations with Bounded Minimum Angle
We consider bounding the cardinality of an arbitrary triangulation with smallest angle : We show that if the local feature size (i.e. distance between disjoint vertices or edges) ...

Delaunay Refinement for Piecewise Smooth Complexes
We present a Delaunay refinement algorithm for meshing a piecewise smooth complex in three dimensions. The algorithm protects edges with weighted points to avoid the difficulty po...
