How do I set up something that is black on the left and white on the
right? Before you answer, I want the demarcation at x=0, and the max &
min extent in x can vary wildly, and it's a BLOB! (The arms can swing
out.) This question is no-brainer if we are talking an unchangingsphere
but perhaps not solvable w/ pov if we are talking a blob of varying
extent.
The following solution won't work, because it is reflected over the x=0
plane.
pigment { gradient x
pigment_map{
[0 Black]
[0.5 Black]
[0.51 White]
[1 White]
}
}
If I translate the image map, this won't work either, because it will
start at min extent of the actual figure, something impossible to
determine with a blob.
