| Abstract | We propose a real-time rendering method for dynamic scenes under all-frequency environmental lighting. To render the object surfaces illuminated by environmental lighting, the product of the environmental lighting, the visibility function at each shading point on the object surfaces, and the BRDF is integrated. Our method represents the environmental lighting and the BRDFs with spherical Gaussians and represents the visibility functions with spherical signed distance functions (SSDFs). Although these representations enable us to render scenes under all-frequency lighting in real-time, the previous method is limited to static scenes since the computational costs of SSDFs are quite high. To address this problem, we propose an efficient calculation method of SSDFs by approximating the object geometries with a set of spheres. This makes it possible to render fully dynamic scenes where the viewpoints, lighting, and BRDFs can be changed at run-time and objects can move, rotate and be deformed in real-time. |
