Excerpt from Principles of Architectural Perspective The first chapter of the book is devoted to definitions and to the theory of perspective in general. In the second chapter are given ten elementary problems covering all of the descriptive geometry that is needed to completely solve a problem in perspective. All of these elementary problems will be found to depend directly upon the problem of finding the intersection of a right line with a plane. The student is advised to make himself thoroughly familiar with the contents of this chapter before attempt ing the solution of the practical problem which is given in Chapter III.

Excerpt from Principles of Architectural Composition: An Attempt to Order and Phrase Ideas Which Have Hitherto Been Only Felt by the Instinctive Taste of Designers John Beverly Robinson It is, of course, a question whether architecture, in our time, will improve in its artistic character, or will deteriorate until that character is wholly lost. There is a tendency in each direction. The evil influences which cause the tendency downwards are numerous, and have been discussed on many occasions - the commercial demands which control nearly all costly buildings, the ignorance of the public men whose opinions control what is erected for the State, the changed position of the architect from that of a salaried artistic supervisor to that of a highly paid fiduciary administrator, and the disappearance from the modern world of the ancient instinct towards ornamental design. The good ih fluence which causes a tendency upward is merely the slowly developed sense of our own short-comings caused by that very self-conscious, comparative study of ourselves and of the past which has injured architec tural design in the past but as we believe in the past only to help it greatly in the future.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ... CHAPTER X. SHADOWS IN PERSPECTIVE. 187. -- Shadow is the obstruction of light. If any object is lighted from a single source, the rays of light which fall upon it will be interrupted and a portion of space extending indefinitely behind the object will be deprived of light. This darkened space is called the invisible shadow of the object and will take the form of a cone or cylinder, the elements of which are the rays of light tangent to the object. 188. --The intersection of this invisible shadow with any plane is called the visible shadow of the object upon the plane. When the term shadow alone is used it usually means the visible shadow. In Fig. 81, 0 represents an object in space lighted by solar rays coming in the direction indicated by the arrow. The sun being at so great a distance, no appreciable error will be made if its rays are assumed to be parallel. Thus the invisible shadow of the object will take the form of a cylinder (C). The intersection of this cylinder with any plane (P) will be seen as the visible shadow (as) of the object upon the plane. 189. --If the object is reduced in size until it becomes a single point, its invisible shadow will become the single ray of light which has passed through the point. Thus the shadow of any point upon a plane is where the ray of light through the point pierces the plane. 190. --The invisible shadow of a straight line will be a plane made up of all the rays of light which pass through the line. Thus the shadow of a straight line upon a plane, being the intersection of two planes, will be a straight line. In Fig. 82, a'b' represents the shadow of the line ab upon the plane P. The shadow of any point (d) in the line, will be where the ray of light through the point crosses the shadow of...
