No those are not... :P
Those are some fine examples of what ppl can do with lots of patience
and they are really really great. But no professional graphician will
do a scene using those math primitives. Just take any 3d modelling
program and try to find a perfect sphere primitive... they will output
a triangle mesh or a nurbs surface... :P
Of course all the features I added in my wish list where intended to
make povray a "professional" level raytracer. I hope that this fine
piece of opensource software someday will make this next step towards
being the definitive renderer...

As I told U I did those benchmarks, and other comparisons too...
