摘要 阴影映射是通过计算机图形的模拟,在3D场景中加入阴影的过程。在实际的应用中,需要解决该算法产生走样的问题。本文采用一种基于入射角的阴影映射算法,有效解决了阴影生成的走样问题。 Shadow Mapping is the process of adding shadow to 3D scenes through the simulation of computer graphics.In the practical application,we need to solve the problem that the algorithm produces aliasing.In this paper,we use the shadow mapping algorithm based on incident angle to dispose the aliasing issue.
