double TimeToCollision	(	IMovingObject &	mobj,
		IObject &	sobj
	)			const [inline]

Computes time to first collision. If no collision occurs then return infinite;

Returns:

Time duration to first collision

Here is the call graph for this function:

PointsVector CollisionPoints	(	IMovingObject &	mobj,
		IObject &	sobj
	)			const [inline]

Computes points which are in objects collision. If no collision occurs then return empty container. Points are ordered by time.

Returns:

Container with colliosion points.
