9. Subdiv Surfaces
Subdivision surface modeling—also known as subdiv modeling or sub-Ds—combines the freedom and utility of poly modeling with the smooth surfaces of NURBS objects (Figure 9.1). Subdivision surfaces share many attributes with smooth poly proxies: At the base level, both types of models have a low-res poly control cage, which surrounds a subdivided (smooth) higher-res mesh. The key difference between these model types is that subdivision surfaces are nested like a set of Russian dolls, with finer and finer detailed surfaces controlled by the rougher surfaces around them.
