Fluid Simulation in Bullet [?]

Post by xissburg » Thu Oct 15, 2009 4:27 pm

Is it currently possible to simulate fluids in Bullet? SPH? Velocity fields?

Thanks.

I'll tag along - I'd like to create a stream of water flowing down (by gravity), changing direction by ramps and such.

Can Bullet simulate such fluid physics?

Thanks for pointing that out. Had a few troubles to build but I got it. It runs very slow on CPU (around 3 fps) but runs very fast on GPU (not sure how many fps). But it doesn't use Bullet (??).

And about fluid-rigid/soft body interaction? It doesnt use Bullet but would it be easy to integrate it with Bullet so that we get this interaction? And how much more processing would it need? And about rendering the fluid surface?

Thanks.

The SPH fluid integration with Bullet is on the TODO list:
http://code.google.com/p/bullet/issues/detail?id=296

If you feel want to work on this integration, please have a look at the soft body/cloth interaction. Contributions are welcome. Otherwise, please be patient :)
Thanks,
Erwin

I'm interested in this topic. Are there any news concerning the SPH fluid integration with Bullet?
