VC++下OpenGL图形基本框架

利用opengl程序来实现椭球体的绘制，设置窗口的背景色，实现顶点、线框、面的方式显示，可以对椭球体进行旋转以及沿着XYZ轴缩放，以模拟现实

Raytracing example implement a basic ray-tracer and render a simple scene using ray casting and local shading. The starter code sets up a scene comprising of an ellipsoid and a plane, being illuminated by a point light source. Your job is to render the scene by implementing code fragments required for object intersections and Phong shading.

“虚拟地景生成系统”是基于Windows2000系统和Visual C++ 6.0平台，利用基本OpenGL函数编程技术开发的三维可视化成果。它通过简单的DEM（数字高程模型）数据，建立格网模型、再根据光照强度、高程值及有关数据建立数学模型，生成晕渲，再将它投影到平面上，达到模拟现实地貌起伏的效果。 本系统采用XP风格界面，清新自然。它具有透射/正射投影切换、漫游、缩放功能。支持分层晕渲、比高设定、平移、旋转、翻滚、视野调节、雾化、纹理贴图(显示/隐藏)等诸多功能，单幅、1MB大小的DEM数据生成速度为秒级，浏览时无停顿。-"to the virtual scene generation system" is based on Windows 2000 and Visual C 6.0 platform, using the basic function of OpenGL programming technology developed by 3D visualization results. Through simple DEM (Digital Elevation Model) data, establish grid model, in accordance with light intensity, elevation data and the value of a mathematical model, generate Hillshading, then it projection plane to achieve realistic simulation of the effect of undulating topography. The system uses XP style interface as well. It has transmission/switching are overhead projectors, roaming, zoom function. Support for layered Hillshading, compete against the creation, translation, rotation, rolling and vision adjustment, atomization,
