In previous, the supplementary plane was adopted to help the visualization of the hidden rays on shadow boundary. A new illustration of the hidden ray-tracing is presented here by introducing the extended complementary air region satisfying the edge condition. Hence it may easily found that hidden rays on shadow boundary are governed by the same tracing rule of ordinary rays on lit boundary.
