Elimination of Hidden Lines in 3-D Signal Graph for Machine Condition Monitoring

针对设备工况监测中三维信号图形的显示问题,提出了一种用画家算法实现的三维信号图形隐藏线快速消隐算法,并对方法的程序实现作了介绍.

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.
