这个程序是我的一个图形学课程的小作业，其中实现了Bresenham直线插补算法、Barsky线框裁剪算法、平行六面体自消隐算法以及绕任意轴的旋转算法。-this procedure is a small graphics course operations, which achieved a Bresenham interpolation algorithm, Barsky wireframe cutting algorithm, parallel hexahedron since blanking algorithm and around the axis of rotation of arbitrary algorithm.
