Principles of digital image synthesis - Andrew S Glassner

Image synthesis, or rendering, is a field of transformation: it changes
geometry and physics into meaningful images. Because the most popular
algorithms frequently change, it is increasingly important for researchers
and implementors to have a basic understanding of the principles of image
synthesis. Focusing on theory, Andrew Glassner provides a comprehensive
explanation of the three core fields of study that come together to form
digital image synthesis: the human visual system, digital signal
processing, and the interaction of matter and light. Assuming no more than
a basic background in calculus, Glassner transforms his passion and
expertise into a thorough presentation of each of these disciplines, and
their elegant orchestration into modern rendering techniques such as
radiosity and ray tracing.
