Abstract
A computer graphics display system for rapidly shading areas on a raster scan screen is described. With the system, the host computer provides the display controller with the parameters of a set of component trapezoids which cover the area to be shaded. The paper gives an algorithm for use in the host to decompose an arbitrary polygon into component trapezoids and it describes a microcomputer based controller to shade the trapezoids.
