Near-Surface Atmospheric Scattering Rendering Method

Abstract:
Targeted at the problem of the near-surface perspective lacking authenticity and timeliness, the author puts forward an optimized algorithm for real-time atmospheric rendering that takes Rayleigh scattering and Mie scattering. It simplifies multiple scattering in the existing pretreatment atmospheric algorithm, and doesn’t affect rendering. At the same time, on the premise of not affecting the timeliness, it extends calculation of lookup table to multiple frames, to reduce time for looking up and calculation. Experimental results show that, this system has good display and can be applied in various fields.
