The Limits of Human Vision

Abstract

A model of the perception limits of the human visual system is presented, resulting in an estimate of approximately 15 million variable resolution pixels per eye. Assuming a 60 Hz stereo display with a depth complexity of 6, we make the prediction that a rendering rate of approximately ten billion triangles per second is sufficient to saturate the human visual system. 17 different physically realizable computer display configurations are analyzed to understand their visual perceptions limits. The displays include direct viewCRTs, stereo projection displays, multi-walled immersive stereo projection displays, head-mounted displays, as well as standard TV and movie displays for comparison. A theoretical maximum triangle per second rate is also computed for each of these display configurations.
