Abstract

The principal objective of this thesis is to demonstrate that the concept of hierarchical graphics composition is a workable model for creating, editing and managing computer-generated two-dimensional color pictures. As a result, a powerful tool has been developed which is easy to use and yet requires minimal hardware. There are several things we want to accomplish in this paper: to introduce the concept of this hierarchical model and compare it with two other hierarchical models, to present the main algorithm of intersection of two convex figures whose edges can be circular arcs or straight line segments, to show an example using this graphics composition package, to describe the software and hardware environment for this package, and to include a user's guide for the package.
