The first object participating in the intersection
Whether the first object is entirely inside the second
The second object participating in the intersection
Whether the second object is entirely inside the first
The index of the colliding shape for the object a body
The index of the colliding shape for the object b body
Magnitude of the overlap on the shortest colliding axis
The shortest colliding axis (unit-vector)
The overlap vector (i.e. overlapN.scale(overlap, overlap)). If this vector is subtracted from the position of a, a and b will no longer be colliding
An object representing the result of an intersection.
