1. A system comprising:
at least one processor configured to perform operations comprising:
projecting primary rays at reflective surfaces in an image to generate a cluster of primary hit points;
generating projections of carrier rays through the cluster of generated primary hit points;
generating secondary rays from carrier rays that intersect an augmented object;
generating a render target texture of intersections between the secondary rays and the augmented object;
and
reconstructing reflections of the augmented object on one or more of the reflective surfaces in the image from light values sampled in the render target texture.
