Abstract: FXAA is a post-processing anti-aliasing algorithm.Because it is an edge detection algorithm based on image pixel,it causes a lot of unnecessary anti-aliasing computation.In order to improve the performance of anti-aliasing,an improved anti-aliasing algorithm based on FXAA (IAAFXAA) was proposed.The depth and normal of the relative view are saved into the texture.The algorithm extracts depth and normal information from G-buffer,and uses depth and normal information to perform more accurate edge detection.A large number of experimental results and analysis show that while ensuring the good anti-aliasing effect,the proposed algorithm can determine the anti-aliasing region more accurately to generate high-quality boundaries,and avoid excessive blurring of images to improve image quality.

Key words: Deferred rendering, G-Buffer, Anti-aliasing, Edge detection
