ABSTRACT:
A method for generating images that appear as complex three-dimensional surfaces when viewed using a stereoscopic viewing system, using only a minimum amount of data to define the images. The stereo contours of a complex three-dimensional surface are drawn using a three-dimensional computer drawing system and three-axis input device. The drawing is viewed with a stereoscopic viewing system using, e.g., a CRT where the left and right eye images are time multiplexed in sequential fields and liquid crystal shutter glasses synchronized with the CRT display. Simply by drawing closed loops in space, filling the closed loops with color, and drawing a minimum number of other stereo contours, an image is created which appears to define a complex three-dimensional surface. The image creates a mental perception of a complete solid object by providing to the observer's eye only the minimum cues required by the brain to create stereo objects with complex surfaces, taking advantage of the stage of human neural processing in which the images the eye sees are coded into similar stereo cues. The normal image processing of the brain is in effect substituted for the complex mathematical processing of prior systems to create objects perceived as having three-dimensional volume and surfaces. Therefore, the tedious design and computations required by present systems to produce a full computer graphics description of the object are eliminated, thereby substantially reducing the time required to draw three-dimensional objects as well as the processing requirements where the images are processed by computers, thus making it possible for artists to create three-dimensional images as simply and intuitively as two-dimensional images have historically been created on two-dimensional surfaces.
