Re: Collision with interior of a collision shape.
If CD is possible between any two given shapes, inverting one of them (swapping 'inside' for 'outside') would just mean that colliding circumstances before become non-colliding and vice versa. Sensible contact generation would probably be a little more involved, though.

Re: Non-SPU multithreaded collision detection
Thanks Erwin, good to hear I was on the right track! Am currently hacking the Compound collision algo but will check out this branch.
Cheers

Re: Sphere Box collisions
Out of interest, did anything come of this?

Re: Major contact stability improvement
Sounds like some awesome work - how about you share on github?
Thanks

Non-SPU multithreaded collision detection
Has anyone any experiences/code to share in hacking Bullet to do multithreaded collision detection? I remember reading somewhere that at least one group of people had hacked their own dispatcher together. (The SPU code gives quite different results to the normal dispatcher particularly when dealing ...

Re: Arrow flight modeling
At a guess, air resistance is what keeps the arrow pointing in the direction of flight, given a massive arrowhead. So modelling a torque on the object based on its velocity vector may be a good place to start. Let us know how you get on!

damped Generic6DofSpringConstraint under gravity unstable
I've noticed that the Generic6DofSpringConstraint does not reach an equilibrium state when gravity is applied. I'm using the code pGen6Dof->enableSpring(5, true); pGen6Dof->setEquilibriumPoint(5, 0); pGen6Dof->setStiffness(5, 200); pGen6Dof->setDamping(5, 0.0005); pGen6Dof->setAngularLowerLimit(btVe...
