示例1: genContactsB

// a corner can be, early out:
if (transformedSpherePosition.squareMagnitude() > b.getSize().squareMagnitude())
return;
// Otherwise, find the closest point on the cube.
// For any axis, it will be the cube half length on that side if
// the sphere's position is further than the half length. If not, it'll
// just be the component on that side.
