The VISIDEP (TM) method of three-dimensional display has been applied to object and cel animation by the author. The VISIDEP method differs from other three-dimensional imaging techniqu1s in that it gives parallax information without requiring viewers to wear special glasses. The illusion of movement created by the various forms of animation has been used in motion pictures since the late 1800s. Based on persistence of vision, animation requires artwork replacement at a rate of 12 to 24 changes per second. Through the use of perspective and shading animators have been able to add a three-dimensional "look" to their films. This two-dimensional depth is "read" py the viewer through a learned process based on their cultural and sociological background. Until recently a true three-dimensional "look" could be achieved only through stereo-scopic filming. Most of the systems available require special projection and viewing optics. The subject matter is usually live-action. Only one3 animated feature film, "Star-chaser" (TM), has been produced using a stereoscopic process.
