The object definition looks rather strange: A box is about 0.2 units
wide in x direction, but the spacing you use is about 0.0004 so you
have an overlap of about 500 layers at each surface point. You can't
actually look through that anyway even if you set max_trace_level to
the maximum value of 255.
