The blended images was rendered simultanously on my 1.5
GHz Athlon PC (Red Hat 9 Linux). They were both finished
after 10 hours. (But one finished an hour before the
other IIRC.)

AA was set to 0.3 (or maybe 0.2).

Yes. The the centre of the "sphere" was too dark in
the shadow version and too bright in the non-shadow
version. I could have rendered with shadows and with
brighter ambient light settings, but I wanted the
dark _shaded_ areas to remain dark.

Radiosity is another solution, but I suspect such a
rendering to be waaaay tooo sloooow.
