ABSTRACT
The human eye takes a cue from shadows not only in judging where a light source is located, but also what an object is made of, how far away it is and how it relates spatially to its surroundings.
As well as being one of the most important aesthetic considerations for a lighting artist, in the world of CG shadow rendering is also one of the most important technical aspects to get to grips with. From the initial choice of algorithm, shadow casting can be an extremely computationally intensive business, so
shadows is vital, as is then learning how to break these rules and trick your way to convincing shadows in a fraction of the time.
