A description of the parameters might be a documentation sort of thing, but seeing what changes to parameters do is sort of a How To thing...

I am working on a few demonstration scenes for the following:

  1. a scene demonstrating when radiosity could be used to improve realism.
    • When I was new to POV, I didn't know when to use radiosity, and I think different examples showing the difference between using the ambient light for global illumination and radiosity would be helpful in making such a determination.
  2. Using radiosity with lightsources
  3. Using radiosity without lightsources (glowing object method)
  4. Effects ok sky_sphere or background on radiosity
  5. possibly a 10 x 10 grid of images with parameter changes (and render times) to demonstrate some of the main speed/quality ratios.
  6. ???

Input would be appreciated! --Reactor 22:32, 27 December 2007 (UTC)

It makes sense to cover the typical problems and artifacts that people run into, and how to avoid those pitfalls.
Maybe something like a Cornell box for a test scene?
