摘　　要：三维图形变换需要对形体顶点的齐次坐标矩阵进行复合计算,计算繁琐且变换过程晦涩抽象,使用传统的程序设计语言实现图形变换的可视化非常困难。因为在三维图形变换中引入MATLAB工具,利用其强大的矩阵运算能力和丰富的图形处理能力,能够快速准确地计算矩阵和输出图形,清晰直观地展现图形变换的方法和过程。A very complex calculation of homogeneous coordinate vertex matrix is needed in 3D graphic transformations. The process of calculation is complicated and obscure. It is very difficult to realize 3D visualization by using the traditional programming language. MATLAB is introduced into 3D graphic transformations. By using its ability of powerful matrix operation and rich graphic processing,we can calculate matrix and output graphic rapidly,and show the method and process of graphic transformation clearly and intuitively.
