Abstract
An apparatus for optimization of a simulated three-dimensional effect for film or video when constancy of the effect is desired. The apparatus comprises at least one arcuate support rail. A trolley is affixed movably to the support rail. A remotely controlled variable speed motor is affixed to the trolley for moving the trolley along the support rail. A camera mounting is affixed to the trolley and movable horizontally and vertically with respect to the trolley so that a camera is moved at a constant angular velocity relative to a scene to be filmed or recorded. The angular velocity is defined as linear circumferential speed at a specific and constant radius from the scene, the angular velocity being between 25 degrees per second and 65 degrees per second.
