SIMD for Collision

In a previous post SIMD Matters I discussed the big wins I got from graph coloring to make the contact solver faster. That same approach exists in Box3D. I like to call this approach &ldquo;wide SIMD&rdquo;. The idea is to process multiple work units at the same time. In the contact solver this means solving four contact points at the same time.&#xA;This is different from &ldquo;narrow SIMD&rdquo;…
