Can someone tell me why this object doesn't get white,but only black, though
i assigned an rgb <1,1,1> command?
Many thanks!

#macro etorus(w, h, r) sphere_sweep {
// The factor by which we need to scale
// a b_spline to get the right size
#declare s=1.6;
b_spline
7,
<-w*s, 0, 0>, r
< 0, 0, h*s>, r
< w*s, 0, 0>, r
< 0, 0, -h*s>, r
<-w*s, 0, 0>, r
< 0, 0, h*s>, r
< w*s, 0, 0>, r
// tolerance could be a param if you wanted
tolerance 0.9
}
#end
object {
etorus(19, 1*10, .1)
rgb <1,1,1>
rotate <0,0,5>
}

Actually, the answer is in the message-- the POV-Ray messages, that is. ;-)
When rendered it says: "Quick color belongs in texture. Color ignored." and
"No pigment type given."
Needs a pigment wrapper at the very least. So pigment {rgb 1} would correct
the error. Watch the message stream first, then if it's okay the problem
could just be camera/light/object position or something else that's not a
scripting error.

> tolerance 0.9
Higher tolerance produces worse results. 0.9 is *huge* for a tolerance
value, especially when your radius is 0.1. Try something more like 1e-6 or
just leave the default.
When tolerance is so high, it's very possible that the sphere sweep thinks
that it's in its own shadow, which would cause it to be dark.
Of course, make sure you have a light source, too. =)
