Re: Bullet source code question (OpenCL)
That would depend on the cache architecture. That algorithm was written for Pre-Fermi/Southern Islands class GPUs with more limited caching than we have now. A lot of those architectures have very severe performance issues with uncoalesced access. In general for vector architecture's it's worth thin...

Re: Bullet source code question (OpenCL)
Hi Genscher, That memory layout transformation is standard practice for data parallel execution and vector machines, of which the GPU is an example. Remember that the way the GPU works is that you have some set of wide SIMD threads - each of those SIMD threads contains many work items which access d...

2. Are rigid bodies collisions accelerated throught OpenCL? Or it's just cloth simulation? No. This is just very early work that we wanted to get into the tree quickly for various reasons and to see what changes we'd need to make within the bullet code to cleanly integrate accelerated computation e...
