画等高线（带色彩蒙板），只要你由点的三维坐标，就可以利用这个程序帮你画出立体的模拟图-Draw contour lines (with color mask), as long as you point by the three-dimensional coordinates, you can use this program to help you draw three-dimensional simulation of Fig.

苏大图老师的书，详细介绍了各种各样的光学测试技术及其编程的理论基础。-Soviet FIG teacher' s book, detailing the various theories based optical testing technology and programming.

Very convenient to use, Is a practical method of path planning, FIG simulation speed, distance, amplitude three-dimensional image.
