Abstract
This report describes the generation of synthetic stereo image pairs and a cyclopean depth map using the ray tracing program PoVRay . A ray tracing program produces simulated snapshots of a 3D model, one pixel at a time, by tracing rays backwards from the viewpoint through the image and into the scene. If a ray strikes an object in the scene, the image pixel through which it passed is painted with the colour of that object; otherwise, the image pixel is painted with the colour of the background. By offsetting the viewpoint to the left and right of a central position, it’s possible to generate stereo image pairs. These can be combined with a central depth view, in which pixel intensity is proportional to distance from the viewpoint, by adding fog to the environment. Since the three views are rendered with the same perspective projection, they are in perfect correspondence.
