How to Render: The Fundamentals of Light, Shadow and Reflectivity
by Scott Robertson, Thomas Bertling · Design Studio Press
Robertson constructs shadows geometrically, locating shadow shapes from a light source in perspective, then renders surfaces by reflectivity across matte, glossy, metal and glass. Part one covers light and shadow physics, part two material behavior. Teaches how to project shadow geometry from a point or parallel light source onto surfaces in perspective, which is the only rigorous way to shade an imagined object.
