Add SIMD accelerated constraint solver #154

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

Make the inner loop of Projected Gauss Seidel/SI SIMD and branchless, and 
reuse the same loop for contacts, contact friction and non-contact joints.

GoogleCodeExporter commented 9 years ago 
Initial results show almost 40% increase in performance of the innerloop for 
the 
branchless SIMD implementation.

For some of the  benchmarks, this results in an overall performance improvement 
of 
about 5 to 10%.

SSE/SIMD innerloop has been added and released in Bullet 2.73 SP1:
