The Graphics Group (GG) at the University of Auckland is a research group within the Computer Science Department, with ties to other groups in medicine and engineering. The group's activities cover a range of research areas, including physically-based animation techniques, image-based rendering, geometric modelling, and volume visualization algorithms. While algorithmic efficiency is always an issue in computer graphics, the focus of research by the GG is usually on the quality of the models or images and their physical or mathematical correctness, rather than on raw speed.
