Okay, I'm supposed to construct this 4-mirror apparatus on POV-Ray. Here is the
drawing from which I'm supposed to do this from:

http://i1003.photobucket.com/albums/af151/mbradar2/povrayforumfigure.png

I have it on the -z axis. It is 4 mirrors.. the squares that are darker are the
backs of the mirrors, and the squares that are lighter are the fronts - the
actual reflective surfaces of the mirrors. Light goes in from the left and
bounces through the mirrors and comes out to the right. This is for physics..
polarized electrons and all.

Anyway, on POV-Ray, I have four 'boxes' on the -z axis, but I can't figure out
how to angle them so they look like the picture.. they are more rhombuses in the
picture, but I can make them look like rhombuses just by changing the camera,
can I not?

I have one square near the area of <0,0,-13>, lying flat there on the z-plane.
But I don't want it flat, I want it upright.. however, when I change the
z-variable of the rotation ( like <0,0,45> for 45 degrees), it doesn't just
angle it, it moves it away from its original spot.

How do I angle it without it moving away? That's my main question.

Or is there a better technique to constructing those 4 mirrors? I'm having a
very difficult time with this since I just started using this program yesterday
and my boss was hoping to have this done in a couple of days. He knows I don't
know the program and it's not super important that he have this done because he
has a bare-skeleton version already, but he'd like a cool 3D version since he's
submitting a scientific paper, and he doesn't know anyone who uses this program
so I'm his last resort. So if anyone can help me out with a sort-of-quick (1 to
2-day max) way to construct those mirrors, I would be eternally grateful.
