Add Post Processing Clouds #20
Description
Yeah, why not.
Certainly not going to be fast to work through, but will be interesting to get it functioning.
- Find some method for efficient planet-scale data storage. Can't render clouds for a planet unless there is data...
- Find some method for usable runtime generation of the cloud data (both movement and permutation). Static clouds look bad, mmkay?
- Include cloud rendering into the atmosphere scattering model -- use of scattering/phase angles, volumetric shadows from clouds.
