ABSTRACT
In the past few decades, anti-aliasing method has been widely investigated in the field of computer graphics. Compared with the traditional anti-aliasing method, the anti-aliasing method with temporal coherence can avoid the computational cost of rendering additional samples. However, most of the existing temporal coherence anti-aliasing methods have limitations in performing anti-aliasing of specular materials. In this paper, we propose an optimized anti-aliasing method based on virtual hit point, which can avoid sampling error of specular surface. We use ray-tracing pipeline to render the image and display the results. Experimental results show that our method can achieve anti-aliasing effect with real-time performance.
