Perspective- Mirrored Planes

[mika_land]

Thanks for the explanations @darktiste and @JoesphCow !   After some fiddling  around with the planes I found my answer on my own (for the most part), though your explanations are great (makes it more solid)!  I get what they mean by mirroring now and it's uses. 


I meant to delete this post but I guess it held on. Sorry bout that.
