[patch] speedup BVH creation by 13% #720

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The attached patch speeds up the optimized BVH creation by 13% by removing 
duplicate work - means was calculated twice.

It's against 2.80 but should apply to trunk.

Adding a build-time cache for the AABB centers gave a further 30% speedup. That 
patch isn't clean enough to post however.

Please consider sharing a non-clean patch, someone might be inspired to clean 
it up :)

I would also be interested in having this patch (and cleaning it if it is 
needed)
