This classic study of perspective is an absolute must for any serious students of design, benefiting amateurs and professionals alike. Dozens of examples are illustrated, including parallel, angular, and oblique perspectives, as well as ascending and descending planes. Other images show how to create a “cone of rays,” and add depth and realism to curved objects. The techniques can be used for laying out a garden, predicting the shadow effects of a tall building, and accurately capturing the interplay of angles, light, and shadow.
