摘要
将全局光照模型和球冠光源模型结合起来,利用光线跟踪算法实现了由CSG树定义的任意复杂物体的真实感图形生成,模拟了阴影、透明、反射等多种效果,生成的画面具有很强的真实感,并利用包围框大大减少了计算量。
A complex sky dome light source and a global illumination model are combined together with the ray-tracing to generate the realize scene of the objects which defined by the CSG tree. The experiment including objects shading, transparency and reflcetion are super-realistic. A object surrounding box method and it's algorihm for ray-tracing to reduce CPU time are adopted.
