Computer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer. The development of computer graphics has made computers easier to interact with, and better for understanding and interpreting many types of data. Developments in computer graphics have had a profound impact on many types of media and have revolutionised animation, movies and the video game industry. This book presents current research in the study of computer graphics, including computer graphics and medical image processing utilised in oral and maxillofacial surgery; open-source and freeware tools in computer graphics; fractal geometry in computer graphics and virtual reality; and visual attention in computer graphics.
