....548 Kantner Model hierarchies are an area of active research in the computer graphics community. Wavelets are used to create sets of models of 3 dimensional objects for on screen rendering. As an object moves toward the foreground of an image, more complex models are used to display finer detail (Schr oder 1996). Modeling for control has its own set of requirements. Primarily, simulation and analysis computations must grow reasonably as state dimension increases. In computer graphics, all problems are limited to 2 or 3 dimensions. Additionally, some measure of model accuracy is needed. Is a nonlinear 2 ....

....a coarser signal m (n 1) and its detail coecients in d (n 1) yields extra data to store. For memory critical applications such as compression and progressive transmission, we can circumvent such extra data by skipping the smoothing step of the reduction operation in a spirit of lazy wavelets [38, 43]. Then, m (n 1) contains the even frames of m (n) and thus we have non zero detail coecients in d (n 1) only for odd frames to achieve an exact representation of the same size. The original motion must have (k2 n 1) frames to construct a hierarchy of n levels with its base signal of (k ....

The driving forces behind this development are the challenging demands of computer graphics applications such as the computation of illumination (integral equations of linear transport theory) simulation of material properties (PDEs) and goal directed animation (constrained optimization) ....
