Physically Based Rendering

'Computer graphics, and rendering in particular, is full of beautiful theory. The theory covers physical concepts, such as light fields and the interaction of light with different materials, and mathematical concepts, such as integral equations and Monte Carlo integration. The great thing about computers is that they allow us to build rendering systems based on the best theory. This book turns the theory of image-making into a practical method for creating images.' ?from the foreword by Pat Han ...
