how is a collision event thrown with ode ?

Hey !
I had a quick look at ODE doc and i wonder if it’s possible to know when a moving object will collide and where as soon as possible.
In other words : is it possible to predict where and when an object is gonna collide with an other object before it really collides ?
Plz answer me !! thanks a lot !!

Have never heard that you could that but maybes there a way…theres always a way !

No you cant do that. Best you can do is serialize the state of the engine. Step forward an amount until a collision occurs. Reload your saved state. Step forward a smaller amount, repeat until you have an estimate of the time of collision.

Or simply make the coliding object bigger then it is for real. then it will colide befor it realy dose.
