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

K thanks, that would also explain why I could have sworn to <insert deity of choice here> that I had seen it in SVN before...because it was. ;)

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

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

Re: Building and running OpenCL demo in Nvidia platform

I ended up giving in and just using the CMake build. Otherwise, you end up having to symlink vectormath into the place where the Makefile build is expecting it (or hack on the autotools scripts to make it happen).

Not a problem, sometimes fixes cross each other in the SCM. ;)

Re: [SOLVED] OpenCL GpuSoftBodySolvers (non-SIMD-aware) issu

Latest (as of about 5 min ago) trunk. I didn't see a fix unless you had fixed it in ahother file? I was only looking in btSoftBodySolver_OpenCL.cpp.

About to send up the patch now.

[edit: http://code.google.com/p/bullet/issues/detail?id=546]

Thanks!

Re: OpenCL GpuSoftBodySolvers (non-SIMD-aware) issue

NM I think I found it -- I was wondering about this when I was looking through the non-SIMD-aware code and coulnd't find some of these kernel names. I added some additional error message generation code to CLFunctions::compileCLKernelFromString in btSoftBodySovler_OpenCL.cpp, and see compiling kerne...

[SOLVED] OpenCL GpuSoftBodySolvers (non-SIMD-aware) issue

When I try to disable the USE_SIMDAWARE_SOLVER flag in the OpenCLClothDemo code, I run into a problem with compiling shadesr, First, it appears that the non-SIMD-aware solvers do not actually call buildShaders() like the SIMD version does. Second, when I add a call in the non-SIMD-aware solver to ca...

Intel OpenCL SDK support patch

If there is any interest, I have made the changes necessary to support Intel's OpenCL SDK:

http://www.intel.com/go/opencl

I do not see any obvious link on the Bullet Googlecode page to upload a patch -- can someone point me to one, or describe the usual patch-submission process?

Thanks

Re: Building and running OpenCL demo in Nvidia platform

NM -- found it through your link to the changes above. Grabbing trunk fixes my NVidia OCL issues, and the cloth demo seems to run fine. autotools question still valid -- is the configure script deprecated/no-longer-supported? The reason I ask is that even after running autogen.sh in the trunk, I get...

Re: Building and running OpenCL demo in Nvidia platform

5. CL_PLATFORM_NVIDIA is defined. Where exactly is this defined? I am also using the latest (4.0) GPU Computing SDK and latest drivers (280.13) on Linux/64, and I can't find this define anywhere (and so the NVidia cloth demo segfaults trying to init with MiniCL). @Erwin: I've also run into many pro...
