IMAGE DESCRIPTION:

  Just a boring class :)

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

  My main purpose for this image was to test how povray's radiosity works.
There's only 1 light source (the Sun) in the image, outside the room, so
without radiosity everything into the shadows would be uniformly gray
(no visible corners etc). Also the lamps in the ceiling would be
completely invisible. The radiosity makes all details into the shadows
visible.
  I know the radiosity engine of povray is kinda poor, but it worked
better than I supposed. It makes the image more realistic.
  However, there are little errors in the shadows (like stains of dirt or
something). I could use a better quality for the radiosity, but the
calculation time would have been days or weeks :)  I like it anyways.
  The light source is a 10*10 area light. It makes the image a LOT more
realistic (with a point light the shadows are too sharp).

  There is one thing I realized while doing this image: Ambient lighting
can make an object REALLY unrealistic.
  Let me explain. Look at the trees outside. The shadows are completely
black. I was forced to turn off ambient light for these objects. This is
because normal modifiers just don't work into the shadows (the trees use
bumps and crand). The trees look just flat in the shadow part (while the
illuminated side is very bumped and wrinkled). It looks AWFUL! With
completely black shadows it looks quite acceptable.

  All is done by hand, with a simple text editor. I have used moray quite
a lot, but I don't know... it's just a little too limited :) (of course I
designed the furniture on paper first).
