Publisher's Synopsis
Excerpt from Shades and Shadows and Perspective: A Text-Book Based on the Principles of Descriptive Geometry
The aim of this treatise is to present through a knowledge of descriptive geometry, those principles which are fundamental in the solution of both theoretical and practical problems and, by a formulation of these principles, to arrive at and thus place upon a mathematical basis those rules and formulas which are commonly used in practice.
The method of presentation, which has been developed and tested during fifteen years of experience in the class room, seeks to introduce and substantiate each principle by reference to the simplest form of magnitude. For this reason no attempt has been made at either elaborate or artistic drawings, as these belong rather to the field of application.
