We present a novel algorithm to evaluate and render Loop subdivision
surfaces. The algorithm exploits the fact that Loop subdivision
surfaces are piecewise polynomial and uses the forward difference
technique for efficiently computing uniform samples on the limit
surface. The main advantage of our algorithm is that it only
requires a small and constant amount of memory that does not depend
on the subdivision depth. The simple structure of the algorithm
enables a scalable degree of hardware implementation. By low-level
parallelization of the computations, we can reduce the critical
computation costs to a theoretical minimum of about one {\tt
float[3]}-operation per triangle.
