Dewdney described ways ofĬreating programs for hypercube rotation in the April 1986 "Computer Recreations" column of Scientific American. The hypercube is not that much more complicated, withġ6 vertices and 32 edges. To give the impression of continuous motion in what is called Machines, a cube, with 8 vertices and 12 edges, can be rotated Production and display depends strongly on the number of Vertices and draws the appropriate segments. Wire-frame object, the computer calculates the positions of the Modern graphics computers can produce images very quickly. Should this window be placed slightly higher? Should that entranceway be longer? A turn of a dial can produce the new view and simultaneously make the changes for a new set of blueprints. As an architect takes her client on a tour of a prospective auditorium, she can alter the different features to create different impressions. We can experience what it would be like to walk along a corridor or down a staircase in a building that has not yet been constructed. Architectural and industrial design become dynamic processes as we look at not just a few views but 30 views per second, each slightly different from its predecessor, giving the impression of continuous motion. We can combine a century and a half of animation experience together with modern computer graphics to create and investigate complicated configurations in three-dimensional space. Slow motion and freeze frame techniques made it possible to analyze the motion of a racehorse or the exertion of muscles in lifting a log. The photographs of Muybridge himself, striding up a ramp in front of his camera, could be placed on a rotary device and flipped over and over so that he walked on and on, in a primitive version of a motion picture. Within a generation of the invention of photography 150 years ago, Eadweard Muybridge had used this new technology to alter our perception of time and space.
