Abstract : The DRAWL language provides a simple means of defining a graphical composition and specifying operations on it. A catalog of parts is kept; any defined item may be re-used any number of times. Changes in viewing angle, scale, absolute location, and projection are easily affected in three dimensions via homogeneous coordinate projective geometry. Graphical output is available on cathode-ray tube-displays, digital-incremental plotters, and on-line computer line-printers and remote printing terminals. (Author)
