PhysX FleX v0.25 Sample Demo made available - Real-time unified physics
- Thread starter -SD-
- Start date
okay
I'm running this at 720p on a GT755M (GTX 650 equivalent), and I'm quite impressed by how decently it runs. The fluids kill my framerate, but aside from that this is really cool.
That's odd; the 670 supports CUDA 3.0, so it should work.
Ahh got the recording to work. You have to install ffmpeg to your PC and add the folder "movies" to the root directory of the program. Easy to figure out in hindsight, just have to take a look at the error messages in cmd and play around a little.
EDIT: Also looks like the program doesn't like it when you record in fullscreen

I've studied a few of the techniques used for these demos. Real-time fluid simulation and rendering is basically impossible without serious optimization. That's basically why you'd want to use PhysX's implementation rather than rolling your own. The fundamental equations are simple, but making it fast is difficult.
These demos are very, very impressive. I hope this sort of technology is integrated into the next generation of games. I'm just disappointed it's NVIDIA-only.
Aww yeah, I've been wanting to try this out.
Random question for anyone doing GPU compute - in SLI, can you set aside some memory on each GPU and use it separately for parallel calculations? Say a game only used 4/12GB on each for the graphics, can you have each working on its own 8GB worth of isolated stuff, or is it all just cloned on each GPU?
#1 on my wish list would be to see it applied to the God Game genre. Dropping a meteor to crack open a volcano, stuff like that.

Lovin it.
Is your GeForce driver too old?
It's not working for me on a GTX 580 (with the latest drivers). I get this error: "Could not initialize Flex, selected device is not SM3.0 or higher..."
It's because GTX 580 is a CUDA 2.0 capable card and at least CUDA 3.0 capability is required.

Simply amazing stuff.We need in games please.
I'll buy a game if they have this water simulation and i don't care the gameplay or if i don't like it.Only for the physics

Tried this today, pretty cool stuff. Would love to see these kinds of physics applied to games in real time.
Oh man, imagine this with VR and a six-axis controller (e.g. STEM or lighthouse) as your 3D input. Simple little experiences like throwing a pie at someone would be amazing.
If they have VR support I'll try it out with my DK2 later.
Here's a new "water balloon vs. bullet" FleX demo that has 370,000 particles. Running on 3x Titan X.

They also show a new layered cloth FleX demo.

This is cool and stuff but what I really want to see is a simulation of peeing on a hydrophobic wall

This is a really great demo. Modifying gravity parameters with any of the liquid demos is amazing.

Yay slideshow! Unless you have that nifty Titan X setup of course
Excited for nvidia to implement the per eye rendering for use with the consumer vr hmds. After playing around with this it really drives up my desire to see this kind of complexity of physics in games, though I know that's probably not gonna happen for quite some time :

Nah, just one original titan for now. Waiting for local stock in Canada and then I'll pick up two for VR SLI (whenever that's ready).
It might actually work out ok since it still only needs to do the physics once, it's just rendering twice, and it looks like easy rendering.
Edit: nope, having played with it, the rendering's not quite that easy - a lot goes into converting those points into a fluid representation.

It will happen in some Nvidia sponsored titles in the next coming years and probably an indie project on UE4.
Otherwise... gotta wait till the end of this console gen for such stuff probably.
Wonder what the GPU utilization is for these? Even though we had realistic hair in Nvidia demos back in 2003 with Dawn, it's not until lately where we're seeing such technology in games regularly. So... 2027 or so, we'll have this water in games often and it'll be nothing special.

Pretty loud music track in both of those videos, by the way.
New release that comes with FleX v0.80 binaries, Linux version and documentation. Requires at least GeForce driver v347.25 to work.

Noticed a slight performance increase. That could also be attributed to going from GeForce driver 340.52 to 347.88.

...and that's a huge understatement. There needs to be an exponential increase in computing speed to really enable these amazing physics in games sometime before the end of this century.
I mean, to simulate a measly 370,000 FleX particles in real-time we apparently need three Titan X cards in SLI: https://www.youtube.com/watch?v=e8YdZ1l2MmI#t=1242
I tried running the FleX demo on my GTX 970, but when I boot it up it opens the window, but doesn't display the simulations. If I try selecting some of the later ones they will show up on the bottom left quadrant of the window, but flipped horizontally and vertically, and it won't display any particles. Does anyone have any idea why it's not working?

Didn't see a post about it thought I'd share here, somebody plopped Mario into a small space with various flex materials with some basic physics interaction using the little guy. Runs pretty well too on a single 970 (goes to shit with the water one though). Here's a vid, also download in the description. Alt+enter enables Rift support fyi. Would love to see a new Sunshine with water physics like this. Maybe in a gen or two? lol

Thanks for the information i need to try this.

That was awesome
Aw yea. I mean, I'd pay money for this with VR support and 3d input.

I tried yesterday this demo in my pc with a 960 and i don't have any problems with the water section.Maybe is because i have the physics to run in the cpu and not in the gpu.
