Drawing shadows. 19th-century sciagraphic projections demonstrating how to draw shadows. Sciagraphy is the use of shading and the projection of shadows to show perspective in architectural or technical drawing. These diagrams are from 'Traite de la science du dessin' (Treatise on the science of drawing, 1821) by French engineer Louis-Leger Vallee (1784-1864).
