一种光线追踪算法的程序，利用VB编程，可以显示三维形体的真实感-a ray tracing algorithm for the procedure, and use VB can demonstrate that the photorealistic 3D Shape

光线跟踪算法,比较经典的光线跟踪算法，步骤2-raytracing

基于Windows的光线跟踪算法，较为详细地实现了其效果，对于学习图形图像的人员具有很好的参考价值。-Windows-based ray tracing algorithm, the more detail the effect, and have a good reference value for the staff to learn graphic images.
