在图形模式下显示3D图形绕任意轴旋转的程序，物体的每一个顶点的坐标都储存在外部变量point中了，比如说第一个顶点就是point[0],他的坐标是(point[0][0],point[0][1],point[0][2])。整个步骤我想在程序的注释中讲得很清楚了。-in graphic mode display 3D graphics rotating procedures objects each vertex of the coordinates are stored in the external variables which point, for instance, the first point is a vertex [0], the coordinates of (point [0] [0], [0] point [1] point [0] [2]). I think the whole process in the Notes procedures made very clear.
