yeah, the problem with all of Ron's stuff is the lack of information about calculation times.....

 

pretty though... don't let my clients see those clips!!

Wow, the chemical reaction videos are truly amazing.
I wonder how much time it took to compute the varying_viscosity.avi one considering it looks quite high-rez.
Thanks for the link!

Then again, Realflow is more for liquids. Sure it has limitations but it's still the only one of its category available on the market.

About grid-based fluids, I don't believe they are the holy grail of fx but, without adding more fuel to the fire, you got to start somewhere to improve the system. I know some of us on this list had them for XSI. We got ours implemented in literally no time with some features even surpassing the Maya ones.

The point is, it's no big deal now to program them (I find it harder to justify the need to have them in XSI vs. buying a Maya license).
The good news is there's more and more alternatives around and inspiration for someone who'd like to take the challenge to program them.
I don't expect Softimage to become a leader in the world of simulation (even though I seriously wish they were) and I hope they come up with a nicer particle system way before a CFD one!

Realflow may be great for viscous fluids like water

[kim aldis]

I wouldn't exactly call it great. You can force it but there's limits to what it'll do and if you push it more than a bit it starts to creak at the edges. It's also very limited in terms of texturing. And you can't get it to foam which is quite a limitation.

 but it's lacking when it comes to gases, fire and clouds. With a bit of effort XSI's particle system can produce nice work but it's completely lack of a voxel based CFD solver pushes it way behind the curve. Just about every competing package has a CFD solver either natively or via plugins. I'm really hoping Flowline or thinking particles makes it's way to XSI sometime soon.
