利用C++和D3D写的第一人称场景，用键盘和鼠标控制视野，类CS,The use of C++ and D3D scene first person to write with the keyboard and mouse control of vision, type CS

D3D中的雾效果实现，在地形中实现无效果，模拟真实的自然环境，对远景物体进行低细节处理从而提供渲染效率-D3D fog effect in the realization of the terrain effects-free, a virtual reality of the natural environment, objects with low vision to provide details of the treatment efficiency of rendering

主要实现功能是将远景进行模糊处理。来提高画面的真实度。-The main function is to achieve the vision to blur. To improve the picture fidelity.
