Abstract
Images and respectively associated timing marks are arrayed, as phototransparencies, about a disk. The disk is rotated and the timing marks are sensed. Display occurs either in two-dimensional fashion, such as in a television system, or in three-dimensional fashion such as in a semitransparent full image projection. Associated logic circuitry determines whether the full 3-D transparency is to be produced, in which case all images on the disk are to be illuminated, or whether swim through will occur, either on an image at a time or on a "ham slice" projection basis.
