  What makes you think so? LOD filtering is equally important in raytracing
as it is with any other rendering technique. The problem is that it's more
difficult to implement in raytracing because of all the reflections and
refractions and such.

  The movie Cars was raytraced (instead of scanline-rendered as usual),
and they used mip-mapping and LOD filtering. They used some type of ray
volume algorithms to determine the mipmap levels. It's not trivial, but
possible.
