clipped_by { plane { x, 0 } plane { -z, 3.0 } }
Alone, this does nothing. Use in an object to subtract those planes from it,
such as shown here:
sphere { 0, 4
clipped_by {
plane { x, 0 } plane { -z, 3.0 }
}
pigment {color rgb 1}
}
Also, texturing (pigment, etc.) is not allowed for the clipping object
itself.
