Re: Bullet 2.80 SP1 release :OpenCL rigid bodies & Android

Hi,

I have Bullet 3.0 with openCL running beautifully (fast) in my AMD Radeon HD 7900 with Windows 7 Professional.
I saw the GPU is utilized up to 95% in some of demos.

My question is whether this Bullet 3.0 in OpenCL run on the next-gen game console GPU?
As far as I know the following are the GPUs for next-gen consoles.

AMD Radeon Graphics Core Next engine w/ 1152 shaders [15]
853 MHz AMD Radeon GPU w/ 768 shaders[16]
AMD "Latte" 550 MHz GPU w/ 320 shaders[17]

Thanks in advance,

Suejung

Yes, I work almost exclusively in Linux. What problems are you having?

K thanks, that would also explain why I could have sworn to that I had seen it in SVN before...because it was.

Is the GpuRigidBodyPipeline code anywhere in SVN? Or is it only in this tarball?

Looks like the CharacterDemo project file for vs2008 is missing from this release .

Thanks

Hello,
Great work The performances you gives in your videos are impressive.
We are using bullet for simulating a certain number of ragdolls, and having them running in parallel should be a great improve in our performances

Do you think I could use the code from you demo for my own purpose (using your CustomCollisionDispatcher instead of the default collision dispatcher), or is there some limitations that prevent it ?

If not, then for when is the 3.x planned approximately ?

Hi. I also need to use the code. Did they give you permission? I would like to ask the owner for permission. Is there a website that I can go to where I could get a code without needing permission? Thank you, I appreciate your help.
