实现四个功能：一、图和图素1． 定义屏幕坐标2． 在屏幕中心作下列图素：点 • ； 小方块 ■ ；大方块 ■ ； 圆点 ● 。以上述图素画线二、3． 用DDA法画线段；4． 用DDA法画圆。三、已知如图所示的多面体，其各棱边长均相等。要求1． 用步进法（即+1比较法）编写AB线段生成程序；2． 用法线法编写消隐程序；3． 编写让多面体绕其中心轴线旋转30o、45o、60o的程序四.在三的基础上自动绘制各棱边，自由旋转任意角度-realization of the four functions : 1, maps and map-1. Two definition screen coordinates. In the center of the screen-map for the following : Point# 8226; ; small chunks; large chunks; dots. The above map-line drawing two, three. DDA law with painting segment; 4. With DDA Act Circle. 3, as shown in the figure known polyhedron, its edge longer being equal. Requirements 1. Walking France (a comparison) prepared AB segment generated procedures; 2. Usage prepared blanking line method; 3. To prepare for polyhedron around its central axis rotation 30o, 45o, 60o procedures 4. The three on the basis of automatic drawing the edge, the Liberal arbitrary rotation angle

这是用MFC编写的使用openGL的视口代码。 CChildView::CChildView() 构造函数 CChildView::~CChildView() 析构函数 BEGIN_MESSAGE_MAP(CChildView,CWnd ) 消息映射 BOOL CChildView::PreCreateWindow(CREATESTRUCT& cs)创建窗口重新设置窗口参数 BOOL CChildView::PreTranslateMessage( MSG* pMsg ) 翻译消息 int CChildView::OnCreate( LPCREATESTRUCT lpCreateStruct ) 窗口创建好后进入此函数 完成openGL的初始化 void CChildView::OnSize( UINT nType, int cx, int cy ) 当窗口大小发生改变时重新设置OPenGL的视口参数。 void CChildView::OnDestroy() 销毁窗口 -It is written in MFC to use openGL viewport code.
