Abstract

The state-of-the-art rendering methods, including path tracing, provide photorealistic images; however, the render time can be too long to be used in real-time applications such as video games and virtual and augmented reality. On the other hand, naive rendering methods such as rasterization can provide high-speed rendering instead of high-quality depiction. This paper exploits insights about human visual characteristics to combine a high-quality rendering method and a high-speed rendering method and achieve photorealistic and real-time animation. To exploit an optical illusion that virtually produces slight motion and deformation by luminance changes, we focus on an animation including small geometrical changes and propose a real-time rendering pipeline to add motion information to a photorealistic scene. We evaluated the render time and animation quality by subjective experiments. As a result, the proposed method achieved up to about 570 times faster rendering than conventional path tracing, and parameters to present the illusion and preserve the animation quality have been revealed.
