摘要
简述三维图形中实时阴影的几种算法。主要讨论根据指定条件分别用zpass和zfail算法生成阴影体的算法思想以及实现过程,最后给出该算法基于OpenGL的代码。
Several real-time shadow algorithms were briefly introduced. Based on these, an algorithm using techniques called zpass and zfail was emphatically described, which can save valuable hardware resources while still achieving good image quality. The mechanism and realization by OpenGL of this algorithm were given.
