摘要
文中从采样理论出发,对光线跟踪中走样现象的原因及其反走样原理和方法进行了分析,并根据像素相关性,提出了一种自适应反走样算法。此算法具有简单、快速的优点,能有效地消除图形边缘的走样。
This paper first analyzes the reason for the aliasing in ray-tracing and introduces the principle for antialiasing in terms of the sample theory, and then proposes a method for adaptive antialiasing on the basis of the pixel-coherence, which can eliminate the aliasing of the boundary effectively.
