@Whimsy Collective that should be possible relatively soon. I need to improve the rendering capabilities and my knowledge of GLSL for smoke, and I haven’t tried it yet but I’m going to look into SPH for fluids.

@Enj Have you tried Smoke and Fluids in BGE? I know it is slow having to build external cache.

@fraincoisgfx
Thanks! We have found that the compositor node is pretty inefficient and could certainly benefit from an OpenCL speedup. Unfortunately I need to spend all my time on the BGE particles for now. As my code matures I hope it can serve as a launching point for integrating OpenCL in Blender. I think one of the hardest parts is getting the libraries loaded and setting up the devices cross-platform. After that there would be a lot of low-hanging fruit :)

@Martin
I wrote you an email :)
Just to be clear for others reading though, right now rendering isn’t really possible since this is all in the game engine. I take screencasts of playing in the game engine, but I still desperately need some good looking material to demonstrate!

I have a twitter account, its enjalot, but I’ve let it fall off… perhaps I will dust it off this weekend

@enj

Sweet, I’ pop in and out on #blender and #blendercoders (like to hang around) . Sure I would love to help you out w/ artwork and stuf for your demo’s. I’m sending an e-mail to you so you get my email and we can talk there, or if you see me on IRC it’s “aermartin”

do you have a twitter acc?

if you set up the initial scene and explains what you need, I can do the rest in blender. model/animate, composite as best as I can and optimize for best results/fastest render. And then I can send it back to you for render w/ your OpenCL patch/SRC code.

Cheers, keep up the good work, and I hope it goes well with the thesis/studies.

sadly for me, I’m not too interest in BGE but more in internal, simulation and for sure Compositor node.
But this is incredible, it is good that someone finally is getting into openCL w/ Blender. hopefully it will be used to speed up some tools, Compositor node really need some speed up improvement

@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.
