Gaze-Contingent Volume Rendering
Gaze-contingent display (GCD) [148, 486, 520] has been used in a number of guises for many different applications. One of the original drivers of its development was the need, in flight simulators, to reduce the computational cost of generating images, in order that sufficiently high display rates could be achieved. By tracking the pilot’s fixation point, higher resolution rendering could be employed only around a small fraction of the display area; outside of this region, blurred images could be shown and, provided that the tracking system responded sufficiently quickly to the pilot’s eye movements, no visible deterioration would be experienced.
