Publisher Summary
Finding the outline of multiple areas, defined by closed boundaries, is a common problem for a number of applications in computer graphics. Two-dimensional coverage for a group of radar sites can be determined by finding the envelope of a set of circles. This chapter discusses the outline of a group of two-dimensional regions. Each region is a closed boundary in two dimensions. The outline of the circle set has many short connected arcs or scallops. A direct analytical approach is desirable for creating region-boundary data sets at a resolution much higher than a typical frame buffer can display. ...
