Could you be a little more elaborate?
All I could find is this:
Naiad is a dynamics solver and a simulation framework capable of producing animations of dynamic bodies including:
- liquids
- large and small bodies of water
- breaking waves
- splashes and foam
- accurate viscous liquids featuring buckling, coiling and bending motion
- high degree of creative control while preserving realistic fluid motion
- gases
- fire
- smoke
- explosions
- particle effects which can be coupled with other dynamic bodies, including fluids
- rigid-bodies which can be coupled with other dynamic bodies, including fluids
- soft-bodies which can be coupled with other dynamic bodies, including fluids
…I can only say “WOW” to that, but how is it related to Blender? Are there any plans to integrate this with Blender? Is this just something you’ve found while browsing the internets? Are you one of the programmers? Do you think this should be added to Blender? (well, that’s obvious).
WOW though.
I’m going to download the movie now…
gotta love that node gui!
is there someone who can make a mac build ?
Okay, I’ve read some more about it. It’s a closed source product. Too bad 
(only the samples and the studio product seem to be open source, not the actual code for doing simulations)
Still, nicccee…
yeah only the GUI is open source… however, a very interesting approach…
The end comment by the tall swede to the right (was both swedes?) … the idea could be implemented in blender smoke , and physic branch,
why calculate on a big domain, let say if I do a huge cube as domain.
it breaks it into 15x15x15 smaller cubes and only calculates individual cubes if a smoke particle enters it… then alot of the sub-domain can be free and dont do anything.
could speed things up:D if it 's not already working in that way
Yeah, that’s why Field3D is such an interesting project 
Being lazy…is there anywhere they publish a reference of the physics api they talk about in the video like the renderman reference manual?
