Adaptive Multi‐view Radiance Caching for Heterogeneous Participating Media

Abstract Achieving lifelike atmospheric effects, such as fog, is essential in creating immersive environments and poses a formidable challenge in real‐time rendering. Highly realistic rendering of complex lighting interacting with dynamic fog can be very resource‐intensive, due to light bouncing through a complex participating media multiple times. We propose an approach that uses a multi‐layered spherical harmonics probe grid to share computations temporarily. In addition, this world‐space storage enables the sharing of radiance data between multiple viewers. In the context of cloud rendering this means faster rendering and a significant enhancement in overall rendering quality with efficient resource utilization.
