Abstract
Three dimensional (3D) image projection is described. In one aspect, each projector of multiple projectors generate a respective composite of an image. With respect to any particular projector, the projector's corresponding composite image encapsulates multiple vertical slices of the image. Each vertical slice in the composite image represents a particular portion of the image for projection by the projector onto a specific area of multiple areas on a screen. The size of the specific area is a function of a width of a viewpoint of multiple viewpoints, wherein the viewpoint is linearly positioned with the specific area on the screen and the projector.
