Three varieties of realism in computer graphics
James A. Ferwerda · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
This paper describes three varieties of realism that need to be considered in evaluating computer graphics images and defines the criteria that need to be met if each kind of realism is to be achieved. The paper introduces a conceptual framework for thinking about realism in images, and describes a set of research tools for measuring image realism and assessing its value in graphics applications.
