3D hierarchies for animation

Geometric representation associated with computer-assisted modeling has proven to be very usefull to visualize and understand the structure and behavior of a wide spectrum of entities (Foley et al. 1990). But if we examine the scope of the current 3D geometric models, we notice that they tend to embrace a static view of the information structure. In this chapter, we are particularly interested in stating the requirements for the modeling of complex 3D environments with mobile components. Such a modeling approach has to integrate a dynamic view of these components such that specific goals can be acheived in space and time. A key requirement is to provide a representation of relative motions and this can be addressed through the use of hierarchical modeling.
