Highly realistic rendering of complex lighting interacting with dynamic fog can be very resourceintensive, 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.Attribution-NonCommercial 4.0 InternationalCCS Concepts: Computing methodologies → Ray tracing; Rendering; Parallel algorithms; Distributed algorithmsComputing methodologies → Ray tracingRenderingParallel algorithmsDistributed algorithms10.1111/cgf.7005112 pages
