I have succeeded in making shiny spheres but I am failing to make one of
them white. When I make one white, it is not shiny.
I am using white light, but when I change the color of the light, then the
color of the sphere changes (naturally).
I have shiny white plastic in my house so I know it exists in 'real life'
and I assume POV-Ray can also do this.
Below is my code which does not work. Any assistance is appreciated.
Thanks,
Hershel

#include "colors.inc"
#declare Width=6;

Well, yes and no. You did make the white sphere shiny, which looks
fabulous. Due to the radiosity, however, it also now reflects the green
sphere. When seen with the whole scene, this does not look so great, IMHO.
Is it possible to achive the shininess of the white sphere without this?
Thanks,
Hershel

nice scene, well all the radiosity does is make them glow a little,
what I added was: reflection {2.0 22.0} to the white sphere,
try adding no_reflection to the green spheres{1}I removed the radiosity
from this example.
Does that help?
Gary

Sorry I took so long to respond--I don't have much time for ray-tracing AND
my family has been sick. Anyhow, thank you for your help--I now have very
close to what I want and I can experiment to get the final product.

The scene is a graphic representation of the system of Sphiros (or sphirot)
which are a basic concept of Jewish Kabbalah. There are ten sphirot and
each one in turn contains all ten in miniature etc. ad infinitum (the Jews
have been dealing with fractals since the dawn of time :) ) . This scene
shows the bottom, blue, one containing all ten. If you're interesting to
learn more, here is one source:
http://www.aish.com/spirituality/kabbala101/Kabbala_3_-_The_Ten_Sefirot.asp
Here is a site with another image of the sphiros (made by yours truly):

hmmm.. verry interesting, I'll have to read some more about that.
I'm just glad I could help a little.
