Comment on Particles in BGE Update: GLSL, more options by enj

@Martin thanks for the support! It’s certainly a goal that my continued improvement in OpenCL will rub off on other devs :)
I’ll certainly be working on this for the next year since it is the basis of my Master’s thesis. I don’t have a paypal button up, maybe I will at some point… but if you’re feeling generous even a little bit of your graphic design talent would be more valuable!

I’m on gtalk and IRC all day, my email is on my about page and I’m enjalot in the blender IRC channels.

@blenderificus

You’re always commenting the same blender stuf as I am ;D but 1 post before.

@enj

Thanks, I’ll actually will update in the coming weeks! I can give you a comment and you can check it out later w/ update videos and images!! everything done in blender, even the logo design.

enj I totally agree! I’ve done just simple sample code with OpenCL and nothing w/ blender so I can’t really contribute *yet*
But what I would love too see is a couple of devs starting to implement OpenCL to blender, and I think you are way in the front line. I hope you continue to devs and Is there a way to donate money? I dont see a paypal button anywhere.

Bullet is getting OpenCL in 3.X , and I’ve seen Bucarellis demos w/ LuxGPU vids. it’s awesome.

keep up the good work! and I hope you accelerate the particles in BGE, then if you become OpenCL fluent you could try and teach module owners to Optimize nodes, simulations etc.

Cheers

@Blenderificus yeah I've been talking with phonybone about his work, I think I have much to learn from him! It's not clear that the node system could be made to perform well enough in real-time though. Thanks for the video link! @Martin thanks! I'm still learning so much in the BGE and about particles that I haven't had time to look at stuff outside it, but I do hope that my work will set up OpenCL in Blender so other aspects can be sped up. Related projects like Luxrender and Bullet are adding OpenCL acceleration too. Thanks for the par4all link, there is a lot going on! btw I like your art/blog!

also, have you seen this OSS project.

http://www.par4all.org/

they’re planning to implement OpenCL opt. for source-to-source conversion from C/C++/Fortran to OpenCL.

You seem to be quite experience w/ OpenCL, I’ve just checked out the early demos from Apple, and khronos and read some source code that uses opencl.

that particle demo is off the hook! have you planned to take a look at the compositing nodes besides BGE? I think them can be massive sped up by utilizing the GPU instead of CPU.

nice work!

awesome work so far. 60fps with that many particles in blender is !!!!!! And the ability to use textures/movies/animated-procedurals for particle color(or other properties) is going to be an extremely cool addition to blender. Thank you for your hard work, and thanks to the DSC for supporting it!

Given your focus on the particle system, I wonder if you’ve seen the other amazing particle addition being added to blender. Particle node-based system, AMAZING, much like your work.

Hey Cedric,

Unfortunately I don’t have windows handy to test right now. You can look in the cmake/FindOPENC.cmake file to see how it is searching for OPENCL_LIBRARIES

You could try finding out where OpenCL.lib or OpenCL.dll is on your system and adding a LINK_LIBARIES(C:/path/to/OpenCL.lib) into the CMakeLists.txt in part1/

wish I could be more help
Ian

Hi,

I am a beginner using cuda and opencl and I’ve tried to setup correctly cmake on my computer, but I am getting an error
“CMake Error: The following variables are used in this project, but they are set
to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake file
s:
OPENCL_LIBRARIES
linked by target “part1.x” in directory C:/Dev/advcl/part1″
I have a quadro FX 3800M with Notebook Developer Drivers 257.21.
I rebooted after the installation.

Do I need to set something special? Is OPENCL_LIBRARIES not set correctly by cmake?

Thanks

The effect at 3:20 of the video is especially cool.

Thanks for the suggestion Paul!
I’ve tried it out and re-written this tutorial using the C++ bindings, and you’re right I find them much cleaner as well.
