Untested (and I don't know RIB well) code:
// POV-Ray SDL:
intersection {
difference {
sphere { <0,.5,0>, 1 pigment { rgb <1,0,0> } }
sphere { <0,.5,0>, 1 pigment { rgb <0,1,0> } rotate z*120 }
}
sphere { <0,.5,0>, 1 pigment { rgb <0,0,1> } rotate z*240 }
translate <1,2,3>
}
# Pixie RIB:
Surface "matte"
AttributeBegin
Translate 1 2 3
SolidBegin "intersection"
SolidBegin "difference"
AttributeBegin
Color 1 0 0
Translate 0 .5 0
Sphere 1 -1 1 360
AttributeEnd
AttributeBegin
Color 0 1 0
Translate 0 .5 0
Rotate 120 0 0 1
Sphere 1 -1 1 360
AttributeEnd
SolidEnd
AttributeBegin
Color 0 0 1
Translate 0 0.5 0
Rotate 120 0 0 1
Sphere 1 -1 1 360
AttributeEnd
SolidEnd
AttributeEnd
I don't want to start a drawn out POV vs. RIB comparison - I'm not
qualified to do so even if I did want to. But, having used both, I will
say that neither is a replacement for the other and that POV suits my
needs better.
