Come on Newtek. Pay this guy to help to improve LW dynamics!

It's an old link that's been linked many times before, Ron works for ILM and i don't think Newteks staff budget could quite afford it... :)

Not only does ROn work for ILM but some of his work has been the base for alot of Maya's fluids. Meaning I doubt we'd see Fedkiw working with NT even 'IF' NT had it in the budget for someone like him just for fluids.

Not that it helps matters, but the coincidence of timing is pretty interesting: I just found out one of my classmates works at ILM and is an ex-student and direct underling of Mr. Fedkiw in the fluid sim department. :hey:

Some time I really ought to walk over to Fedkiw's office and say "hi", but this was more directly related to the topic at hand... :p

What you need weepul is kidnap your classmate, and make him do an open source fluid solution for LW :devil:

Man I would kill to transfer and study under Fedkiw, but alas I'm stuck at C.U. with no massively brilliant fluid prof and me wanting to work with fluids.:grumpy:

Hell, get blender. Its free and it can do this:

These can be exported to LW.

Larry - easily imported? That's some impressive water flow there!

There is nowhere written how long these simulations took to calculate.. There are just the end, rendered effects.. If you imagine that complete renderfarm is needed (yeah, that would be nice to use renderfarm also to pre-calculate dynamics in LW), or single frame calculated in hours, you will give up on so realistics dynamics because it won't useful for regular day by day production..

Yeah Blender transfer to LW fairly easily. I have used Blender for a few projects almost painlessly. Naturally its learning to use Blender with its whacky gui that is the most bizzare part of the issue but you should be able to get up and running with Blender fluids->LW in just an hour or two of watching tuts.

Oh and as for how long that demo Larry showed took to calc, well 'if you have to ask you can't afford it' as the old cliche goes. Seriously though I honestly don't remember what he said the calc time was for that scene but it was LOOOONNNNNNNGGGGGGGGGGGG! Look for the Blender fluid demo vid's, they mention render times with them.

I've played a bit with blender and its fluid sim stuff in the latest version. Overall it's remarkably fast. Obviously if you want to sim a massive scene like that tidal wave one, it's going to take an awful long time, but there are a couple of fluid sim tuts out there that on my dual-core MacBook Pro sim in pretty nearly realtime. So while I don't think it's realistic to expect _everything_ to sim in realtime, it's also not realistic to expect _everything_ to take 70 hours to sim either.

Plus it's free on all kinds of different platforms. No reason not to take a look at it if you want that kind of functionality except the time to get used to the wacky interface.

duke, I'm no doubt being stupid, but what exactly is that supposed to be showing? Non-penetration of the liquid or something?
