Sketchpad Demonstration

Alan Kay, another recipient of the Turing Award, has taken a  copy of the earliest known movie showing Sketchpad in operation and has added a commentary to explain what it is happening. That presentation is available here.

Sutherland’s Patents

Sutherland holds 60 or more patents. Most cited is his 1975 patent entitled, “System of Polygon Sorting by Dissection,” a system for subdividing three-dimensional polygons to sort for the purpose of determining visible parts of polygons, for determining shadows and portions of polygons obstructed by semi-transparent surfaces, and for determining polyhedral interpenetration (when shapes intersect each other).
