ut of its parallel position, this apparently-hidden vanishing point appears, and strikes the horizon at adistance from the centre of vision, depending on its angle, asalready explained. Thus :— In Fig. 59, AB on left side shows the base of a cube inparallel perspective, while in Fig. 60 AB has been… … Fig. 60. Will proceed to horizontal line to left of C.V. Weascertain the positions of these points. Example 1.—Draw a square (side 4) lying on ground; sidesmake an angle of 45° with picture plane, and the angletouches the P.P. at a point 4 to the right: scale \ = V. DRAWING.
