Hi,
Taking the simple example from the pov-ray docs :
difference {
intersection{
sphere { <0, 0,0>, 1
translate -0.5*x
}
sphere { <0, 0,0>, 1
translate 0.5*x
}
pigment { Red }
rotate 90*y
}
cylinder { <0, 0, -1> <0, 0, 1>, 0.35
pigment { Blue }
}
}
The docs say "if we eliminate this pigment (the blue) the surface of the
hole will be red".
Any way I do it the hole surface becomes black.
Anybody like to tell me what I'm doing wrong?
I know I could make the cylinder red but I am trying to apply this to a
more complex shape.
TIA,
Graham.
