hat plane. A vertical line drawn through V.P. is the vanishingline for all planes parallel to E. Similarly the vanishing linefor the plane F passes through the two points A.Y.P. and \.V.C is a plane perpendicular to the picture plane, and per-pendicular to the ground plane.I) is a plane… … i ig. uy and is inclined to both the picture and ground planes. Thevanishing lines for planes of this character belong to the advancedstage of perspective; in fact, to find any of these vanishing linesfrom given data belong to that stage, but it is advisable thatthe student in the elementary stage…
