Re: Ifu - cloud simulator and renderer

Some dissertations on cloud simulation/rendering that may give ideas are Harris (2003), Bouthors (2008), and McLoughlin (2012). I think Bouthors was most concerned with rendering cumulus clouds. Might also look at Display of Clouds Taking into Account Multiple Anisotropic Scattering and Sky by Nishi...

Re: Ifu - cloud simulator and renderer

The clouds are saved in relatively straightforward binary, something like this: [ char - file version; here 'A'] [ int - number of triangles in the 3d cloud mesh] [ float *12*number of triangles - the 3d triangle mesh; 3 vertices + normal] [ int *3 - resolution of the simulation grid, x/y/z; here z=...

Re: Ifu - cloud simulator and renderer

Thanks - no other plans for the code. It's been coming together slowly for a few years for personal interest, and I assume it'll keep getting updated every now and then for the same reason. The option for higher-resolution fluid grids (more detailed clouds) is next on the list of updates, and ought ...

Re: Glitch Pictures anyone?

A bug was fixed where moisture was created out of thin air under certain circumstances, leading to what I assume you thought was snow. But then, they're much the same thing, clouds and snow.

Some past screens of issues getting a naive volumetric SSS thing going.
