From the cartoon of the same name, Arnold (the football-shaped head kid, a
girl calls him) as I tried to make him yesterday. I only see the cartoon
occasionally as the channels are changed so he's not going to be perfected
in any way.
With the talk and posting here about Arnold, the radiosity rendering engine,
I had figured I'd try this character out someday to check radiosity in
POV-Ray. It turns out to be a fair choice of a CSG object to do that imo,
colors and all (I say this tongue-in-cheek).
3 images attached; a non-radiosity, radiosity, and non-radiosity with
post_process find_edges applied. The file names are obvious so if they are
out of order... well, anyone can tell the difference probably.
global_settings{
assumed_gamma 2.3
ambient_light 1//.25 // .25 when radiosity used
ini_option "-qr" // + for on
radiosity{
brightness 1.23
count 123
recursion_limit 1
gray_threshold .1
error_bound .123
low_error_factor .246
minimum_reuse .0123
pretrace_start .08
pretrace_end .001
}
post_process {
posterize { rgb 20 } // separates colors
find_edges{ 1.25, .25, .15, 2, .25, rgb 0 }
}
}
The (point) light source was changed from bright white to orange when going
from no radiosity to radiosity so there could be better coloring since the
sky was contributing so much blue. In other words, I haven't attached the
one without a light because it was with that blue sky and also haven't tried
a hemisphere of light sources yet.
