I think what the parent comment was saying is that the smoothing algorithm used in subdivision modeling is very similar to bezier. Actually, subdivision surfaces are very similar to B-splines [1], but are much more convenient to use than NURBS -- which require the modeler to maintain consistent rows of control points throughout the model. ILM's use of patch modeling in films like Jurassic Park are incredible examples of working around these constraints. (I believe they side-stepped the continuity issue with their proprietary "enveloping" software which allowed them to blend discontinuous B-spline patch surfaces together.) Love this post btw -- extremely impressive / educational. 1: http://graphics.pixar.com/library/Geri/paper.pdf http://graphics.pixar.com/library/Geri/paper.pdf
