Homogeneous Media

I implemented a volumetric path tracer for multiple monochromatic homogeneous media with absorption and multiple scattering. The algorithm includes phase function sampling, next event estimation, and surface lighting via BSDF evaluation.

Heterogeneous Media

I extended the volumetric path tracer to support chromatic heterogeneous volumes using null-scattering. This allows rendering of volumes with spatially and spectrally varying densities.
