Abstract

An stop motion animation sequence of a tangible object is made by the steps of making a series of drawings representing three-dimensional object to be animated in various sequential positions; sequentially embodying the drawings on a projection medium such as motion picture film or video; displaying the projection medium at real time to see if the motion depicted by the drawings is the desired motion; and repeating the foregoing steps until the desired motion is realized. Once the drawings depicting the desired motion are completed, transferring each drawing onto a transparent material such as celluloid (commonly used in animated cartoons) so that an identical series of drawings representing the object in the various sequential positions thereby exists on the transparencies. The transparencies are then sequentially attached in the same location to a stationary indexing jig located between the three-dimensional object to be animated and a viewer or camera such that both the transparency and the object can simultaneously be seen by the viewer or camera. The object is then posed in confirmity with the drawing on the transparency as seen through the viewer or camera; and the object is then photographed in its posed position on a stop frame basis. The next transparency in sequence is then used to reposition the object for the next stop frame and this process of repositioning and stop frame imaging continues until the sequence is complete, thereby yielding a finished stop frame work for projection/display purposes.
