Heavy use of physics website.

[AquaGeneral]

It is not a game but it is a simulation website. Complete with videos and even demos.

You should give it at least a look at.

Demo Rigid Body Simulation on GPUs: http://www.iii.u-tokyo.ac.jp/~takahiroharada/projects/rigidBody.html

All physics lovers will love this, why the hell is there no replies and only 2 or 3 views?

[Jokker]

I'm a physics lover.

I didn't like it.



It's not that is wasn't good, it's just that...it doesn't have a point. It's just a simulation. You need more than a simulation...at least a more complex one... =\

[c--b]

As far as I can tell it doesn't work on ATI cards :/

[Stigern]

Interesting stuff, going to try it later when I get home. :)

[Amynue]

Cool demos:eek:

Runs great on my GF 6600Gt :D

[chumkid]

If they're just demos and not interactive in any way, they're not very interesting. The demos wouldn't even run on my computer, but the screenshots looked nice.

[Stigern]

It was actually quite effective, it could handle alot of rigid bodies, I had like 4000 of them and it was at 33 fps :)

[AquaGeneral]

It sort of proves you need something other the a GFX card and a Processor to calculate physics.

I changed it to my processor and graphic card to both calculate physics simultaneously and it dropped to 25 FPS when there where 5095 Rigib body actor chess pieces.

My PC specs are Intel Core 2 1.86Ghz, Nvidea Geforce 7600 GS, 2 GB of Ram.

Some of the videos show of some extremely complex water simulation.

Massive number of GPU simulated rigid bodies and particles at a cost.
Mildly unstable.

Unfortunately, it requires a higher end nvidia card.

on my 8800 GT:
16,384 particles in 3D at 256 FPS
4,097 chess pieces (rigid bodies) at 160 FPS
947 bricks at 300-600 FPS

http://www.iii.u-tokyo.ac.jp/~takahiroharada/

Also the pic has 768,000 particles using the distinct element method.

Holy... hell...

that's downright staggering. Epic find!

[geel9]

Wish I could run it. Darn 256mb of RAM.

[rocketeer]

Wish I could run it. Darn 256mb of RAM.

Bahaha! I beat you with 510mb of RAM! (Yes, I mean 10, not 12)

[zalo]

I might as well post my other specs since that also affected the sim.

512 megs of graphics memory (HAH!)
4 gigs of real memory
Intel e6850 3.0 Ghz
32 bit Windows XP Professional
Blue LEDS

nice computer! I wish I had one of those. :)

[Whef]

Simulation doesn't work for me.

[Wrestler#1]

Huh? Did you guys download another program to run these simulations? Because when I try to run the cudaparticles it says that the cudart.dll is missing and the particleOnGPU doesn't even give me an error.
Help?
E:OK now I donloaded the newest nvidiadrivers that even have cuda support and it still doesn't work.
Oh, my specs: just look at my signature :p joke

Nvidia geforce 8800 GTX 768mb muhwahahalol (dxdiag says that it has 2015mb :D)
3gigs of DDR2 RAM
intel dualcore 2x 1,86 GHz
Vista Ultimate 64bit SP1

[Muntu]

Agh, how lucky I am. This piece of... computer can't even run tetris well, and you give me such awesome games which, ofc, would run well with my OWN, now dead, computer. STOP IT!

Why did it die?

In fact I have no idea. It just won't turn on.

Yet another draw back in Vista. For some reason Cuda particles are not supported in Vista, yet.

Might go on my other XP system and have a try.

Edit: Same thing occurs on XP.

Intel Core 2 Duo E6850 @ 3.3GHz
3.5GB of DDR2 800MHz (32bit stops it from becoming 4gb)
GeForce 9800GTX 512MB @ Core 762/Shader 1905/Memory 2300 (effective)
Windows Vista - Home Premium SP1

Oh they are supported! Nvidia made special cuda drivers. Just google for cuda and one of the first links is the nvidia cuda driver downloadpage

[looseskrewz]

How do you change the model, and the number of particles?

I just have the bunny with 16000 something particles.

My computer eats this up like it's candy.

P4 3 Gig
NVIDIA GeForce 8800 GT
1.5 Gig RAM

The CUDA NBODY demo is also AMAZING!!

I just wish I new more about C++ cause I would like to add a few features to the code....such as a save feature.

[Ryu Hinote]

Woah, that's one brilliant find Zalo.
So many particles and rigid bodies :eek:

That Blue LEDS make the difference. Without them you couldn't even archive 20 fps.

[Wrestler#1]

Wow, people, guess what I've seen on the last site of this forum!

Well, now we have better graphics cards, that are way cheaper.

Then how are you on the forum? :confused:

[Muntu]

Then how are you on the forum? :confused:

I'm on my parents computer :P
So... First days as a mod, just thinking if it would be better to keep this thread open? Or should I lock this and let you discuss about the demo in the old thread?

I wasn't even around back then. Maybe we could merge the two?

[Virtue]

Merge, I say!
And.....

That's on an (overclocked) 7900GS!

[meow-muffin]

Can anyone make a vid for us mac users and people with bad computers? :)

[Muntu]

Good idea! I, uh.. TRY to merge them two now :D
We'll see the results in a min.

E: OMFG! It was easier than I thought! :O

[Odellus]

Holy shit. (http://www.iii.u-tokyo.ac.jp/~takahiroharada/projects/millionParticle.jpg)

[kotsoft]

it uses 5 gpus. (4GPUs for simulation, 1GPU for rendering)

[Odellus]

It would be complete overkill if they added CryEngine 2 graphics, plus a shader that made it look like water, and then decreased the size of the particles dramatically so that it would be life-like.

[Dan]

Meh, errors with vista...

[SGorilla]

I try opening his demos but they don't work, just crash. Using Vista and the 2.0 Beta drivers.

[zalo]

it uses 5 gpus. (4GPUs for simulation, 1GPU for rendering)

But still, even 1 GPU has immense power.
Can XNA can fully utilize this wealth of extra speed?

[Loplop]

Wow, thats sweet :3

Athlon 64 X2 +4200 ~ 2.2ghz

Aye, but not CUDA. AMD/ATI have their own equivalent called Close To Metal though. I haven't seen anything utilising it yet though.

I kno but im sure someone will spite the NVIDIA movement, not particuarly bothered atm, if it comes to it, ill buy a PPU.
