: refracted rays.

  Of course it works for reflections/refractions. If the pixel color
difference threshold is reached, then another ray is shot from the camera.
This ray will (probably) also reflect/refract from the same object, thus
sampling whatever is reflected/refracted.

  However, the problem here was that if there was such a small object/detail
that no ray hits it and thus is not detected, how could it be done so that
it would be detected anyways and rays shot at it. This might be possible
only if this small object/detail is viewed directly from the camera, but not
if it's seen only in a reflection or refraction.
