光线跟踪算法的Opengl实现，效果还不错，可以自己调节观察方向，有兴趣的可以看一下-Opengl ray tracing algorithm implementation, the results were good, you can observe the direction of their regulation, interested can look at

光线跟踪算法，基于opengl，欢迎大家前来下载！-Ray tracing algorithm, based on the OpenGL

通过 OpenGL 实现的光线追踪。里面已经全部补充完毕。(Ray tracing through OpenGL.)
