A GPU-based Method for Massive Simulation of Distributed Behavioral Models with CUDA

Air atom

[NoDoubtFilms]

Makes sweet, complicated 3D video, then edits the video of it in Windows Movie Maker?

[michaelpmalin]

Why does this video look interlaced?

[Hionimi]

Sooo, what kind of system was used? I mean, what are the specifications?

[bobsonenzo]

Basically, programmers are magicians

[TitanaMaster]

@bobsonenzo yes we are!

[Crazymecrazy12]

just a question: What is the render time?

[ber85it]

@Crazymecrazy12 No specific graphics engine, just OpenGL. The particles are billboards.

[Noah1989]

@Crazymecrazy12 I guess it's realtime. so the render time for this was about 3:27 ;-)

[Crazymecrazy12]

@Noah1989 :o

[jpmorgan187]

neat!

can you simulate the atoms in my brain, thus prediction my future thoughts?

[DjAralo]

espectacular!

[Dilophodd]

Oh.. God... is this realtime?! :O

[maciejwrotek]

can u simulate molecular dynamics of some large proteins live ?

[ventHARAS]

darwinia anyone?

[jafanello]

Cool!



[jafanello]

Cool!

[nrasandun3]

How did you do this? It's a great work. Can you tell me how can I learn to do Massive Simulations like yours.

[KoRMaK1]

@nrasandun3 Learn to program, learn inheritance and OOP for programming, and find the algorithms you need. This uses a Boids algorithm. Each particle gets some CPU time to decide where to fly based on its surroundings. So for every frame, the 130k bodies all get to "think". So that is 130k calculations right there. Sounds big, but modern graphics cards can handle it if you use something like CUDA

[nrasandun3]

@KoRMaK1 Thanks a lot

[abbed8]

with what language? i.e C++ or C etc.

[ber85it]

@abbed8 C++ (OpenSteerDemo as 3D environment) and Nvidia CUDA for the hardware acceleration of particles.

[b1tTutorials]

@abbed8 Why you dont use OpenCL it can be running on your Nvidia but on AMD Cards to. :)

[abbed8]

Did you make this?

[ber85it]

@abbed8 Yes. This is a demo of my ms thesis project

[scoutknifez]

what is the English word for 'hey dude this is fucking awesome and i want to see more of your work!!!' ??

[DKM101]

@scoutknifez

I believe it's "BALHRAHGHRAHGBALRHG". West coast dialect, of course.

[Cheesecake2k]

Yeah. But can it run crysis? XD

[ilhadosmacacos]

if will make games 10 times better than crysis in future

[DasJev]

you mean if crysis can run cuda?

>NO

Can Cuda run Crysis?

...120times

[MINIMAN10000]

1:30 Its the future of racing games, volumetric dirt! But really that would be so cool.

[kraj0t]

absolutely awesome, I look forward to seeing this techinque or voxel in games using cuda... that would be so interesting

[Bosoa]

Astoned!!does the library publicly available?

[Zalo10]

That's absolutely incredible! The sheer volume of things computers can simulate these days is just staggering.

[RavingKunaiX]

Are those billboard images or sphere meshes? OMG

[ber85it]

Billboards.

Is possibile to use meshes with opengl geometry instancing. You can see it in my other video about the simulation of a fish school.

[AnnoyedDragon]

How are there not more comments on this video? This is incredible.

[teichg]

Great work!
