With the development of antialiasing technique in the 3D scene, it has been widely used in aviation and flight simulation, 3D games, virtual reality and other real time rendering applications. In order to solve these problems that still exist in current anti aliasing technology consumptions, such as lacking edge partially, distortion because of excessive ambiguity, a new anti aliasing technology based on SRAA(Subpixel Reconstruction Antialiasing)and deferred shading is proposed.At first, store the position, depth, normal and color information of the 3D model into the G buffer (Geometry Buffer);Secondlysample each pixel of model, at the sametime conduct joint bilateral filter combined with normal and depth information to calculate mixed weight of each pixel; Finally, compute each pixel as a weighted mixture of color value for rendering the whole model scene.In this process, involving with the geometry information of each pixel avoid excessive ambiguity better.Translate the original 3D data into 2D forlighting calculation by using deferred rendering, improve rendering performance actually.
