Pixar's Renderman uses the reyes algorithm. Afaik its much like 
scanlining but divides the objects into a grid of sub-pixel 
micropolygons which makes detailed displacement mapping possible.
But due to its nature it cannot render realistic shadows, reflections 
and refractions.

There are also some approaches to memoy coherent raytracing (normal 
raytracing always requires access to any part of the scene) but from 
what I know they only work when you dont have complex lightning like 
radiosity or hundrets of light sources.

But complexity in raytracing can also be achieved with other rhings than 
meshes like isosurfaces for detailed landscapes.
