要求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。-Asked first of all draw a number of beautiful three-dimensional graphics, and 3D transformation matrix based algorithm, so that graphics on the keyboard or mouse under the control of geometric transformation. The purpose of this study is to make students understand three-dimensional graphics rendering methods, to consolidate understanding of geometric transformations, to master three-dimensional graphics in VC to achieve geometric transform method.
