HTC will probably not answer this but I ask anyway...
I'm assuming that the plane models are logically broken down into a tree of 3d rectangle that roughly match the shape of the aircraft, and if bullet intersects any of these boxes, it registers a 'hit'. Is this assumptions correct?
If so, is it possible for a bullet to intersect the hit 'rectangle' and not actually hit the plane, or vs-versa, and a bullet hit the plane but not intersect a rectangle?
Thanks
