Abstract
Game data is rendered in three dimensions in the GPU of a game console. A left camera view and a right camera view are generated from a single camera view. The left and right camera positions are derived as an offset from a default camera. The focal distance of the left and right cameras is infinity. A game developer does not have to encode dual images into a specific hardware format. When a viewer sees the two slightly offset images, the user's brain combines the two offset images into a single 3D image to give the illusion that objects either pop out from or recede into the display screen. In another embodiment, individual, private video is rendered, on a single display screen, for different viewers. Rather than rendering two similar offset images, two completely different images are rendered allowing each player to view only one of the images.
