Thanks, owl, but the question was not aboute SAT. For exaple I have 2 static bodies, i.e. their velocities is 0. But they can rotate and they can collide at some time. So how can I get this time?

Thanks. Sadly - but see the only way - decrease time steps.
Also I can do the following - given two line segments I can predict their TOI in current frame even if they moving with rotation. But math that I use - is toooooooooooo complicated - there're tons of sin/cos, so for real time sim with many objects this method is not suitable.

I've read some moderator talking about radial swept-volumes (yet denoted as quite complicated). You might want to ask about that.. and post me back lol

Yeah, I've read your article, but I'm true dummy and I didn't understand a half. I hope I'll dig it someday. Thanks.


I've just published a new one on collision detection which covers continuous rotating bodies:

Hope its useful! :)

Cheers, Paul.
