1988 – Ivan Sutherland
Citation
For his pioneering and visionary contributions to computer graphics, starting
with Sketchpad, and continuing after. Sketchpad, though written twenty-five years ago, introduced
many techniques still important today. These include a display file for screen refresh, a recursively
traversed hierarchical structure for modeling graphical objects, recursive methods for geometric
transformations, and an object oriented programming style. Later innovations include a "Lorgnette" for
viewing stereo or colored ../images, and elegant algorithms for registering digitized views, clipping
polygons, and representing surfaces with hidden lines.
