I put together a video testing MSAFluid using Processing vs. FluidSolver using Flash.
My computer I’m using isn’t fast at all, so there is a definite difference in performance.

* Windows XP Pro desktop
* Intel Celeron Processor: 1.6GHz
* 2.0 GB RAM
* NVIDIA GeForce 8800 GT Graphics Card
* Projector: Dell 3300MP

I think Flash comes out ahead in this scenario. - Test Fail

I wrote a little more in my blog about it: http://www.cyancdesign.com/2009/05/flash-vs-processing-fluid-solver/

Looks great man. Memo found a bug in CCV which might be why the velocity looks off on the processing version. CCV wasn’t sending the right velocities; it’s fixed on the svn version now. Not sure if that’s why the movement is weird in the processing version. I actually think the processing one is more fluid when using the mouse, but hard to tell.

That makes sense to me. I was getting zero velocity from the touchpoints in processing, but the mouse worked great.
So using the SVN files, is there a guide anywhere on how to compile CCV?
I have no clue on how to use the SVN files, I’ve been relying on the zipped up release but I’d like to know how to utilize the SVN files eventually.
I keep seeing updates to the source and I would like to be able to use it.

I have Microsoft Visual C++ 2008 Express Edition and I’ve tried using it, but I don’t even know if I can use that program or if I need to setup anything in addition to it like the Touchlib compiling tutorial I found (which I couldn’t get working either).

I love this app,

A few points to improve perhaps?!

Is it possible for the sliders at the top to be controlled by touch rather than mousing?

Also can the faders dissapear and reapear when a blob is held in one spot say for 5 seconds?

Also how does the code in the flash version of this app differ from the ripples.swf?  You know the blue ripples app not the one with water and boats but the other one. The reason i ask is that i would love to get this fluid solver.swf working in modul8.  The only flash app i can full functionality whilst inside modul8 is the ripples app.

Has anyone got any ideas?

Thanks.

LOL. what do ya know, compiling instructions:

really great comparison idea and research

I’d have to side with seth on this tho since java has more direct access it should perform better… and seems to run smooth on other videos so look like issue with input.

still amazing tho to see flash 10 doing these things esp on that hardware 1.6 celeron that thing has like 128kb die cache compared to 8mb now :/

keep up the great work we gotta make some more of these

I’m hoping tonight when I get home I can get the SVN files compiled for CCV and get a fully functioning MSAFluid up and running to get a proper test recorded.

Ok, here’s your problem:

the unedited version of MSA fluid for Processing was made for the MSA remote (using an iPhone screen)
that’s why it looks odd. ...

if you dig in the code you’ll see he multiplies all velocities by 0.02, reducing them to almost nothing (because the iPhone screen is so small!)
change that multiplication to 1 or more and you’ll get it’s full feature

hope that helped
I love the tweaks they made to fluid for flash, but it’s no doubt it runs 10x faster under java

theigor, Christian, Seth, you are all absolutely right. MSAFluid rans circles around FluidSolver in performance.
It is a setting the the TUIO library section in the MSAFluid example.

um, where can i download the Multi-Touch app??

Thanks.

YAY

thanks, i can’t wait to try it out

EDIT: After opening it in ‘Flash Movie Player’, it now shows circles wherever i touch, but nothing else :(
