    I've never actually even looked at the POV source and have no idea how
the glow patch works, so I'm not saying you're wrong, but, why ? If I do :

union {
 sphere { -x, 1 pigment { color rgb 1 } }
 sphere { x, 1 }
 pigment { color red 1 }
}


    I get one red sphere and one white sphere, not two red ones. So,
couldn't you, therefore, implement it so that you could do something like:

union {
 sphere { -x, 1 pigment { color rgb 1 } glow }
 sphere { x, 1 }
 pigment { color red 1 }
}

to give one, glowing, white sphere and one, not glowing, red sphere ?
