Abstract:

A deferred render is incompatible with current hardware-assisted antialiasing. This paper proposes a fast antialiasing algorithm for deferred shading. It does edge detection by using the information in buffers, such as position and normal. The final deferred shading image is sampled by the blur factor for all pixels which returns true by edge detection. Simulation shows that, the antialiasing algorithm can effectively diminish objects jagged edges.

Key words: deferred shading, antialiasing, edge detection, super sampling, jittered sampling

摘要：

使用延期着色技术，无法应用硬件对图形进行反走样处理。针对该问题，提出一种延期着色的快速反走样算法。利用缓存的位置和法线信息准确高效地在缓存中进行边缘检测，对边缘部分采用加权抖动采样方法进行平滑处理。实验表明，该算法能够快速地获得效果较好的反走样结果。
