Bullet的应用率倒是还可以
不过杯具的是,他们的OPENCL 加速目前暂时还是基于NV GPU开发的....
因为AMD GPU还没OPENCL驱动....
另外这是至少一个月前的新闻了吧
更杯具的是,Bullet已经出了n个基于CUDA的版本了.......
现在的OCL版本是基于CUDA版本基础上“翻译”的
We have seen a presentation where Nvidia claims that Mr. Erwin Coumans, the creator of Bullet Physics Engine, said that he developed Bullet physics on Geforce cards. The bad thing for ATI is that they are betting on this open standard physics tech as the one that they want to accelerate on their GPUs.
"ATI’s Bullet GPU acceleration via Open CL will work with any compliant drivers, we use NVIDIA Geforce cards for our development and even use code from their OpenCL SDK, they are a great technology partner. “ said Erwin.
This means that Bullet physics is being developed on Nvidia Geforce cards even though ATI is supposed to get driver and hardware acceleration for Bullet Physics. With such a statement we comes to question whether ATI has any kind of OpenCL driver that it can push for its own Physics. Even if they do, Nvidia is far ahead with PhysX and Intel won’t let them accelerate Havok, as this is a good task for Larrabee, whenever that comes. |
