有OpenGL实现的decal贴图，decal贴图技术可实现爆炸、子弹射击等的痕迹效果。程序经测试运行正确。-Realize the decal has OpenGL textures, decal mapping technology can realize explosions, bullets and other traces of fire effects. Procedures have been tested to run

采用条件编译相对路径。用OpenGL直接管道渲染，没有使用Shader。程序中有2个光源，一个静止，一个运动，从而可以更加精确地验证ShadowVolume的准确性。-Compiled using a relative path conditions. Rendering pipeline using OpenGL directly, without the use of Shader. Procedures in the two l

映射倒影的水面源码，效果不错，可以直接应用的游戏中-Mapping surface reflection of source code, good results can be applied directly to the game
