Bullet time

Bullet time (or bullet-time) is a computer enhanced simulation of variable speed(ie. slow motion, time lapse, other) photography used in recent films, broadcast advertisements and computer games. It is characterized both by its extreme permutation of time (slow enough to show normally imperceptible and un-filmable events, such as flying bullets) and space (by way of the ability of the camera angle--the audience's point-of-view--to move around the scene at a normal speed while events are slowed).

This is almost impossible with conventional slow-motion, as the physical camera would have to move impossibly fast; the concept implies that only a "virtual camera," often illustrated within the confines of a computer-generated environment such as a game or virtual reality, would be capable of "filming" bullet-time types of moments. Technical and historical variations of this effect have been referred to as time slicing, view morphing, slo mo, temps mort and virtual cinematography.
