I would like to add an object to a union, but have no/least affect on the
scene.
So far I have: box{-.001,.001 pigment {rgbt 1}}
I'm thinking that as long as the box is smaller than the other objects in
the union and is translated with then, I can keep the auto bounding for the
union small. Does rgbt 1 mean completely transparent, and so not seen in the
scene? Is the box the most optimized object?
Thank you for any help.
