本文用带消隐线的方法在二维平面上来描绘三维曲面，例如波表面等。
This paper describes 3-D curved surface, such as wave-surface etc, on 2-D plane by using hidden-line method.
下面是一个简单的gnuplot例子，它给出了一个具有等高线和隐线消除的3 - D图形。
Here's a short gnuplot example that illustrates 3-d function plotting with contours and hidden line removal.
同时还启用了基本的等高线和隐线消除特性，最终的绘图是利用 splot 命令使用数学库内部的函数来创建的。
The base contour is enabled along with hidden line removal, and the sinc plot is created with the splot command using the internally available math library functions.
