摘要
在计算机上做立体图形时，是通过二维平面来表现的。本文建立了在计算机的二维坐标系上做三维立体图形的一种算法。根据这种算法，若知道空间曲面或空间曲线的方程，就可在计算机上绘出其图形；给出了在ＶＢ５．
In this paper we have come up with an algorithm of drawing three dimensional figures in computers two dimensional coordinates. By this algorithm,we can easily draw three dimensional figures on computers when we have their equations. In the first section,three theorems on the algorithm are presented corresponding to three kinds of different states of three dimensional coordinates. While in the second section, as an example of realizing the algorithm, we present the code (VB5 0) of drawing two dimensional normal density functions figure and the running result.
