Coder Corner

Some years ago I wrote a bit about the Multi-SAP approach in my SAP document. I think I also said I would release some code, but never did. Erwin Coumans tried to implement one version in Bullet, but it’s still marked as “experimental” some years later, and it looks a bit like everybody gave up on that technique - including us in PhysX 3.0.

Well I didn’t.

I still think it’s a very nice method, and very easy to implement once you have a regular sweep-and-prune working. So I’m restarting this effort, refreshing my old prototype, adding some new tricks learnt since last time, etc.

As a teaser, and to show non-believers that yes, it rocks, I quickly added it to my old CDTestFramework, as found in Bullet 2.78. I’ll let you guys test it on your respective machines, but at least here at home, it beats the alternative algorithms in Bullet’s default scene.

Stay tuned…
