This is the third edition of a book that deals with the processes involved in converting a mathematical or geometric description of an object - a computer graphics model - into a visualization - a two-dimensional projection - that simulates the appearance of a real object. The analogy of a synthetic camera is often used and this is a good allusion provided we bear in mind certain important limitations that are not usually available in a computer graphics camera (depth of field and motion blur are two examples) and certain computer graphics facilities that do not appear in a camera (near and far clipping planes). Algorithms in computer graphics mostly function in a three-dimensional domain and the creations in this space are then mapped into a two-dimensional display or image plane at a late stage in the overall process. Traditionally computer graphics has created pictures by starting with a very detailed geometric description, subjecting this to a series of transformations that orient a viewer and objects in three-dimensional space, then imitating reality by making the objects look solid and real - a process known as rendering. In the early 1980s there was a coming together of research - carried out in the 1970s into reflection models, hidden surface removal and the like - that resulted in the emergence of a de facto approach to image synthesis of solid objects. But now this is proving insufficient for the new demands of moving computer imagery and virtual reality and much research is being carried out into how to model complex objects, where the nature and shape of the object changes dynamically and into capturing the richness of the world without having to explicitly model every detail. Such efforts are resulting in diverse synthesis methods and modelling methods but at the moment there has been no emergence of new image generation techniques that rival the pseudo-standard way of modelling and rendering solid objects - a method that has been established since the mid-1970s.
