This paper shows that, for any plane geometric graph G with n vertices
, there is a triangulation T that conforms to G, i.e., each edge of G
is the union of some edges of T, where T has O (n(2)) vertices with ea
ch angle of its triangles measuring no more than 11/15 pi. Additionall
y, T can be computed in O(n(2) log n) time.
