  abstract = {A new approach to subdivision based on the evolution of surfaces under
	curvature motion is presented. Such an evolution can be understood
	as a natural geometric filter process where time corresponds to the
	filter width. Thus, subdivision can be interpreted as the application
	of a geometric filter on an initial surface. The approach closely
	connects subdivision to surface fairing concerning the geometric
	smoothing and to cascadic multigrid methods with respect to the actual
	numerical procedure. The derived method does not distinguish between
	different valences of nodes nor between different mesh refinement
