Abstract: A ray tracer has been developed that synthesizes images directly into the frequency domain. This makes it possible to use a simple vision model to control where rays are cast into a scene and to decide how rays should be spawned once an object is intersected. In this manner the most visible artifacts can be removed first and noise can be channeled into those areas of an image where it is least noticeable. The resulting image is produced in a format that is consistent with many image compression and transmission schemes.
