Yes, you can wrap the whole scene in a union{} and then difference or intersect
that with two planes. The slice is our depth range. Although it may not look
like you wish.

unless you mean focal blur, that is a camera setting that takes some tweaking.

Thinking of it there may be an other way, that depends a bit on your 
scene versus the slice you want from it. Objects can have the options 
no-image, no-shadow, no-refection to hide it from the scene.

A third option is to just not add the objects to the scene that are not 
within the slice of the scene you want.

Yes, some sort of culling script.

Do a loop, grab the min_extent and max_extent of the object, see if the whole
object resides inside the "slice", and if not, then skip it.
