Accelerated Light Propagation Through Participating Media
International Workshop on Volume Graphics, Proceedings of the
Monte Carlo path tracing is a simple and effective way to solve the volume rendering equation. However, propagating light paths through participating media can be very costly because of the need to simulate potentially many scattering events. This paper presents a simple technique to accelerate path tracing of homogeneous participating media. We use a traditional path tracer for scattering near the surface but switch to a new approach for handling paths that penetrate far enough inside thedoi:10.2312/vg/vg07/017-023 fatcat:vfq7bpd6ejaltaf3cee2sofxdm
