Function Documentation

void b2TimeOfImpact	(	b2TOIOutput *	output,
		const b2TOIInput *	input
	)

Compute the upper bound on time before two shapes penetrate. Time is represented as a fraction between [0,tMax]. This uses a swept separating axis and may miss some intermediate, non-tunneling collision. If you change the time interval, you should call this function again. Note: use b2Distance to compute the contact point and normal at the time of impact.
