        where direction is a unit vector, pointing in the direction mapData is travelling

        the direction vector decides what the collision plane will be. for example the collision plane
        of a moving car is vertical, like the surface of a brick wall, in front of the car.

        the returned collisionArray is the heights of the nearest voxel lining up to each (x,y) of that
        plane.
