The ubiquity of computer-generated imagery around us, in movies,
advertising or on the Internet is already being taken for granted
and what impresses most people is the photorealistic quality of the
images. Pictures, as we have often been told, are worth a thousand
words and the information transported by an image can take many
different forms. Many computer graphics researchers are exploring
non-photorealistic rendering techniques as an alternative to
realistic rendering. Defined by what it is not, non-photorealistic
rendering brings art and science together, concentrating less on
the process and more on the communication content of an image.
Techniques that have long been used by artists can be applied to
computer graphics to emphasize subtle attributes and to omit
extraneous information. This book provides an overview of the
published research on non-photorealistic rendering in order to
categorize and distill the current research into a body of usable
techniques. A summary of some of the algorithms as well as
pseudo-code for producing some of the images is included.
