SHADOW OF THE VERTICAL CUT To the light source behind and to the left of it (center projection)

Light source behind and to the left

With such an arrangement of the light source, the vanishing point of the horizontal projections of the light rays F ^{S 1} will be on the horizon line to the left of the straight line perspective, and the vanishing point of the light rays F ^{S will} be above the horizon line.
