In the case of reflectors formed from concave surfaces, the same techniques can be used with some observations. Vertices in the original scene may not map to exactly one reflection direction and thus their reflections cannot be approximated. Ofek and Rappoport note, however, that the motion of such vertices appears chaotic and any of the mapped virtual vertices can be chosen as the reflected vertex.
