Improved Triangular Subdivision Schemes
In this article we improve the butterfly and Loop's algorithm. As a result we obtain subdivision algorithms for triangular nets which can be used to generate G1- and G2surfac...

Local Specification of Surface Subdivision Algorithms
Many polygon mesh algorithms operate in a local manner, yet are formally specified using global indexing schemes. This obscures the essence of these algorithms and makes their spe...

Complete subdivision algorithms, I: intersection of Bezier curves
We give the first complete subdivision algorithm for the intersection of two Bezier curves F, G, possibly with tangential intersections. Our approach to robust subdivision algori...
