Like a lot of people, I've been quite impressed by the radiosity
pictures by Marcos Fajardo (the software he used is now called
"Arnold").

So the question is, is it possible to approach this quality with Megapov
? Kari Kivisalo showed us some interesting findings (and tips) . Here is
an experiment below. The idea was to obtain a "realistic" feel without
cheating too much (like putting lights or light-emitting objects outside
the scene frame). The result is promising. It's not quite there (still
screaming 3D) but close. I apparently solved one nagging problem in POV
radiosity pictures, i.e. some lack of contrast, but giving the texture a
negative ambient value (it's possible and it works !). Using metallic
and brilliance in the texture helped too.
The "glow" seems an artefact of the technique. There's only one light
and a sky_sphere. Pipes are standard output from the madpipe macro.
The image took 1h20mn to render on a PIII 733 (aa 0.3).
The scene code is in binaries.scene-files for those who want to play
with it.
