Special Models for Animation

Often, how an object is defined is intimately woven with how it is animated. We have already seen examples of this, such as hierarchical linkages, special models for fluids, and so forth. This chapter contains a collection of such special models that often have a role to play in animation. These models are implicit surfaces, L-systems, and subdivision surfaces. Some of these modeling techniques have already been mentioned in previous chapters (e.g., implicit surfaces in Chapter 8 and subdivision surfaces in the Chapter 10). This chapter is intended to give the interested reader some additional information on these modeling techniques.
