A video portrait of a Romboy Homotopy, a four dimensional mathematical object. Computer/Camera Technique The first of the computer-generated PHSColograms was produced using the same camera as that used for the real-time objects, however, the image was photographed from a computer monitor. Between each of the nine exposures, the lens of the camera and the "stage" on which the monitor was placed were moved. The image on the monitor was also changed to simulate the perspective change with a real-time object. Because the only light entering the camera was the soft glow of the computer monitor, a special, very fast film had to be used.
