Abstract:

This paper describes a system for generation and representation of computer models of arbitrary three dimensional objects. Three representations are explored which have varying time and space tradeoffs. These representations, which are tailored for irregular 3-D objects, store every input point exactly by using a tree structuring of the object space. Their advantage over more common representations is that they make perspective and hidden-surface elimination less difficult. In addition, one of the representations simplifies the storage of dynamic objects and objects with redundant sub-parts. Author
