Abstract
With present technology, computer generation of color pictures on a television or on a computer output microfilm has become increasingly attractive. Shading algorithms for display of volumes or three-dimensional objects are readily available. Yet the display of essentially two-dimensional patterns calls for simpler, more natural schemes. Computer generation of colored two-dimensional patterns gives new directions to computer graphics software. The intention here is to state the issues and discuss the constraints. Solutions are derived from using known algorithms embedded in a frame especially designed to meet the constraints. Two different and complete schemes of colored pattern generation (CRPG), designed by the authors, are given as examples.
