Abstract:
We present a practical and physically based single scattering model for real time rendering of scenes in participating media. Our model captures various important effects like glows around light sources, the impact of scattering on the appearance of surfaces such as the diffusing of glossy highlights, and the appearance under complex lighting, while maintaining real-time performance and the ease-of- use of the OpenGL fog model. The model can be implemented in modern programmable graphics hardware using a few small numerical lookup tables stored as texture maps. Our model can also be used to extend existing rendering methods such as precomputed radiance transfer to include the volumetric scattering effects.
