Diagram Q. 11 shows in perspective a wayside irm,a man at point A on the ground-plane, and a staff withflag flying. All the details of the house are accuratelydrawn, its nearest edge BD heing 12 feet long. Thehorizon, centre of vision, and distance of the eye from the Solving Problems 263 pietwre are given. Find the errors in the perspective andindicate the methods for rectifying them. The man is. 4eFig. 205.—Diagram Q H. supposed to he 6 feet high, and the flag and smohe to heaffected equally hy the wind. (12 marks.) If BD is 12 feet High, then, as it is a yertical lineand does not vanish, half of it must be 6 feet, the heightthe man should be. We therefore find the halfway upBD. The house vanishes to , so its sides are parallelto the picture, and the slanting bank will have its linesnot vanishing, but drawn with the set square. FB is sucha line. We therefore draw from the point, which is 264 Perspective 6 feet above B, a slanting line parallel to EB. Thisgives us E and EF, 6 feet high, for in parallel perspectiveB is no further away than F. We now carry this heightof 6 feet forward over the edge of the road by a linefrom We transfer point A to the edge of theroad G, and, finding by a vertical GH, 6 feet, we
