English: 15 second time exposure of an animation created by Sketchpad, showing the paths of four points that are constrained by a mechanical linkage. This figure from Ivan Sutherland's famous Sketchpad dissertation was scanned, with permission from Sutherland, using an original paper copy of the dissertation. It has been previously published online in an electronic edition prepared by Alan Blackwell and Kerry Rodden, and freely available at http://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-574.html The original high resolution scans used to create the electronic edition are now being placed on Wikimedia commons in accordance with Sutherland's wishes to make this work freely available. His original research was carried out under a U.S. National Science Foundation Fellowship. |
