Collision accuracy at high velocities

Hi all,

I'm having some troubles with high velocity objects passing through other objects. I've tried tweaking PhysicsSimulator.Iterations (all the way up to 200), which made some small improvements but nothing worth releasing.

Any ideas?

Look at known issues in our manual:
It's section 1, that's the only solutions we have right now.

We are looking into solving this in 2.1 by estimating the time of impact.

We are going to attempt to separate the narrow-phase collision part of the engine just like the broad-phase is and I am going to attempt to create a projected SAT (Separation Axis Theorem) algorithm to enable perfect collisions at any speed. This implementation will also hopefully eliminate object inter-penetration and should allow geometry to be created in real-time. Also for those of you that know how SAT works, don't be afraid that you will lose concave polygon support, I will be including a triangulation system.
