If it is desired to clip an area W defined by its boundary segment in which the vertices of a connected boundary component does not have to be given in a consecutive order against a plane defined by the equation Ax + By + Cz = D, which divides a viewing volume into two parts, visible and invisible, where a visible region M is defined by Ax + By + Cz >= D, such clipping may be achieved by the procedure described herein (see Fig. 1). The description which follows will be with reference to the flow chart of Fig. 2.
