Well, they are clearly using true reflections which are impossible with 
current scanline
accelerators.  One more thing, is that scenes with upwards of 100 million 
triangles
(like the sunflowers) may be approaching the point where raytracing becomes 
more
efficient than scanline rendering - because of the log(n) cost of finding 
intersecting
objects for a pixel may be faster than rasterizing all the polygons.
