首先绘制一些美观的三维图形，然后根据3D变换矩阵算法，使图形在键盘或鼠标的控制下进行几何变换。本实验的目的在于使学生了解绘制三维图形的方法，巩固对图形几何变换的理解，掌握在VC中实现三维图形的几何变换的方法。-First, draw a number of beautiful three-dimensional graphics, and then 3D transformation matrix algorithm, so the keyboard or mouse graphics under the control of geometric transformation. The purpose of this study is to make students understand the methods to draw three-dimensional graphics, geometric transformation to consolidate the understanding of graphics, control three-dimensional graphics in the VC to achieve geometric transform method.
