Simulating the visual environment in real-time via software

Abstract

Computer graphics has been seen since its inception as a means of simulating the visual environment. Ivan Sutherland's binocular CRTs was the first apparatus designed to place a viewing subject in a world generated by a computer. When the subject in Sutherland's apparatus turned his head, the computer generated new images in response, simulating what the subject would see if he really were in the 3-space which existed only in the computer's memory. This paper describes a system which is a practical extension of Sutherland's concept.
