Abstract
An electrical circuit for the graphic processing of resulting contours of several polygonal superposed images stored in memory. Such images, commonly used for numeric machine tool controls, graphically represent a workpiece as sectional contours. The circuit of the present invention, after initialization, determines the inner and outer polygonal contour of the resultant superposed images. The processing speed of the present invention is one to two orders of magnitude greater than the corresponding processing speed of comparable software programs. This high speed processing enables the present invention to represent the effect of a machine tool on a workpiece in three dimensions in real time. By combining this circuit with additional components a relatively inexpensive high speed graphics processor can be created.
