... And that's One Million particles!! #5: ELECTROMAGNETS

Another one in this 'draw as many particles as possible to see if you can make them look nice' series. This time things started to look like weird sci-fi electro-stuff...

You're looking at some simple particles physics running on the GPU, under C# and Managed DirectX. Turns out its pretty fast!

I'm using 1024*1024 textures for position and velocity, and calculate forces passing force-field positions to the shader. With some optimizations or better hardware, i could go up to 4 or 16 million particles. That's just insane!! ;)

Next up is computer-vision on the GPU combined with physics, so the particles will react to what the webcam sees. (ie. a GPU version of my Interactive Logo app)

oh and for those who are interested, this is running on an nvidia 8800 GT, without using CUDA or PhysX.

great result !

i am currently making a particle system with dx10 using shader instancing

hope i could get as good result as you

what is your frame rate ( and resolution ) with your 8800GT ?

@korsakofff69 Drawing small point sprites is really fast. This old demo should run @ 60fps on the old 8800GT.

Check out my newer vids for some more advanced stuff: now I can do particle simulations on a couple of million particles PLUS render another couple of million points/lines PLUS do postprocessing effects, etc. You gotta love modern GPU's :D

Still waiting to get a proper DX11 laptop though; right now only my PC supports it (GTX460). With Compute Shaders you can do so much more...

[korsakofff69]

is that based on "Building a Million Particle System

Lutz Latta" ? dx10 ?

[lievenvv]

@korsakofff69 No, it's actually DX9... Can't wait to start with DX11 though :)

What!? This is surreal. So fast, so beautiful. I want to learn this!

[josephalvizomendoza]

@lievenvv do you have the source code

[Stuna2150]

where can i down load this so that i can render it myself ?
