Lagoa Multiphysics :: Technology Focus


The Inventor of the Lagoa Multiphysics Technology demonstrates his new solver ahead of the Autodesk announcement that the technology will be part of Softimage 2011.5.

Great article! I am glad to see some major steps forward in cloth/fluids in the last year or so. That looks like some of the the most impressive commercially availble sims I’ve seen yet. I’m so glad to see Thiago didn’t keep this proprietary!


There is so much potential application of this, i’m excited just reading about it

Congratz to Thiago.

its good to see this is getting some love on CG talk guys!!

looking forward to having a play with this. :slight_smile:




nice to see this made it here.
the first effect in the video is very interesting.

looking forward to seeing more :slight_smile:


How does that relate to anything, really? : ) Theres finished work section you know…


It´s an inspiring implementation that Thiago has there. I think he did a great job.

But it would be interesting to know simulation times for real world complexity scenes or simulation times at all. The teaser shows interactive rates but this only shows some hundreds or a few thousands of particles at max. For some things this may be appropriate but in vfx production you really never use a hundred particles only so it´s not telling me very much actually.

The implementation seems very cool, but it would be nice to know how millions of particles work or interact and what the performance says in such a case. Otherwise nice article. I enjoyed reading it.


Insofar everybody who used it/tested it agrees that it’s one of the fastest and most scalable solutions around for SPH style work.
It’s seen production use in a couple places well before it even made it into Softimage’s beta (predators in hybrid etc.)


thx first of all for answering. I do not doubt its scalability or production capability (I also read the article and others before :wink: ), also I don´t want to make any point about if that´s good or bad (if things can be done with it, then the simulation times are secondary but they are not unimportant of course), but “fastest, best, greatest, longest, slowest”…these are all subjective and still not tell me anything I´m afraid. They just reflect the users opinion (which is fine and surely a good indicator don´t get me wrong). I simply have a more technical interest.

Fastest compared to what? I am really talking about explicit times. That is something that has not been talked about at all. The teaser is around for quite some time, the technology…well, if you are into the sph topic you knew before what the work was mostly based on. My interest lies therefore in the implementation and this would first of all be the performance times.

How long do for example 10 million particles take to simulate 100 frames including some static obstacles?

The article is revisited, so maybe they include some statistical facts. At least that would be great and I think if it is as fast as people say (and as it´s a particle-spring-sph model it should have a fast “base speed”) it´d be a pusher. On the contrary, if nothing is said about it at all, it makes me wonder why.


It is all very exciting. But I agree, either there are benchmarks or its heresay. :slight_smile:


Shame, story still not up again?

Really wanted to read it.


when is it going to online again?


No benchmarks mind you.
But you can get some sense of user interaction with these feature preview movies and they were recorded ‘live’. Look for the Lagoa stuff.

And just to turn the tables-are there performance benchmarks listed for DPit yet? :twisted:


There kind of is benchmarks for Dpit, and they are impressive.


“impressive” isn’t a link.
I looked on the site-I haven’t found anything yet…


thanks. I have seen all of those videos and I only see very low particle counts, at max maybe 2000-4000 thousand (in the wine scene, otherwise it´s only a bunch or some hundreds). That´s not really saying anything about complex scenes I´m afraid. I am talking of ranges of millions.

There are no simulation benchmarks on the dpit website but I have posted simulation times in the cinema 4d subforum here on cgtalk (10 million particles, coast scnene of trailer, 1:40m/frame). But it´s maybe not appropriate to start talking about my own software when this is about lagoa. I really was interested in its simulation times, just out of curiosity. :slight_smile:

thx guys


dpit looks nice! What it would take to convert you to ICEholic!?
“Dude, just try it once”
“One time is ok” “Its not addicting”
“The first try is free, just download the trial”

and soon you`ll be attending ICEholic gatherings with Thiago and Helge! Buahah! : )


Us softimage users would love you for it! Best way for you to get into the autodesk market is to make plugins for autodesk products too. :applause:


hehe, well, maybe I will have a look but it would take some serious interest (and me liking ICE programming capabilities) to make me port dpit.
