| Abstract: | By the covering technique in computer graphic display, a hidden line eliminating algorithm for 3-D signal graphs is proposed. Every curve is defined as a ploygon with each edge lined in foreground color and the center filled in in background color. Then they are displayed in order of depth from the viewpoint. As each curve is a non-transparent face, the curve displayed later will cover the overlapping parts of those displayed earlier. Hence the hidden lines in the graph are spontaneously eliminated. |
