| description | This paper is a manual for an implementation of Logo graphics primitives in Lisp on the MIT Lisp Machine. The graphics system provides:
Simple line drawing and erasing using "turtle geometry"
Flexible relative and absolute coordinate systems, scaling
Floating point coordinates
Drawing points, circles, boxes, text
Automatically filling closed curves with patterns
Saving and restoring pictures rapidly as arrays of points
Drawing on color displays, creating new colors
Three dimensional perspective drawing, two-color stereo display |
