Martian sandstorm

Now a fully interactive volumetric sand storm, probably somewhere on Mars.
This marks an intermediate milestone following months of research into volume rendering. It uses finite differences solver for a fluid dynamics equation, some additional research into graphics pipeline on a Mac and iOS.
Note the shadows, they depend on volume density, and also note the unbounded nature of volumes. Other methods would produce visible banding artifacts.

Unexpected volumetric clouds

I was playing with code that I am testing to produce fluid dynamic effects, and I came across a weird cloud generating setup.
The advection part is failing at some point here and causes gas density to freeze in some regions of the map. It remains static and appears as a cloud, and I think this can be further improved to produce realistic looking real cloud. What's missing is a better phase function, and shading based on anisotropic scattering of different wavelenths.
