| (Intermediate) results of the convexification of a tetrahedral mesh. From left to right: the convex hull of the mesh; the nonconvex polyhedron between the convex hull and the boundary of the mesh, which has to be tetrahedralized; and the mesh together with imaginary tetrahedra generated by the tetrahedralization (only edges of imaginary cells are shown). |
