Abstract
A method for generating stereoscopic images includes obtaining image data comprising a plurality of sample points. A direction, a color value, and a depth value are associated with each sample point. The directions and depth values are relative to a common origin. A mesh is generated by displacing the sample points from the origin. The sample points are displaced in the associated directions by distances representative of the corresponding depth values. The image data is mapped to the mesh such that the color values associated with the sample points are mapped to the mesh at the corresponding directions. A first image of the mesh is generated from a first perspective, and a second image of the mesh is generated from a second perspective. The first and second images of the mesh may be caused to be displayed to provide an illusion of depth.
