Real-Time Physics Simulation Forum

Hidiho just wanted to pass by this quite interesting forum.
I have been dabbling with water simulation lately and thought that this might be the right place to deepen some stuff and maybe add some more 2d rigit body physics to my little app.

Just thought this might be the right place to show of my small particle based fluid solver.

It not yet optimized for speed.
The plane is mapped on a torus but rendered as a heightfield.
Comments are highly welcome.

Has anyone of you a good suggestion how to extract the surfacelevel of this thingy? Maybe Setlevel methods or using the particles somehow?
