Clouds qualitative simulation

structures at various scales

The idea is to use directly this knowledge to generate convective phenomena, like cumulus clouds and billowing smoke are. This allowes to separate the scales: larges bubbles account for large range air motion, while waves and vortices lying on a bubble surfaces are just locally advected.

We indeed work on several scales:

You wonder what is the relation with texels ? There is one. Both a texel and a bubble (primitive to be rendered in both case) introduce complexity in a scene by providing a `dressing' of large simple shapes...
