Hi there,

I'm very new to povray and I'm supposed to create a room for a computer
science class I'm taking. I'm trying to put a window into one of my walls
but I can't get it to show up. This is what I have:

#declare wall=
union{
box{<-1,0,5> <9,8,5>}
pigment{color LightBlue}
}
object{wall}
object{wall rotate<0,90,0> translate <-6,0,4>}

#declare window=
difference{
box {<-1,0,5> <9,8,5>}
box {<2,3,2.5> <6,6,2.5>} texture{Glass}}
object{window}

The entire wall turns into glass, and I've tries all sorts of dimensions.
I'm sorry to bug you with a beginner's question, but I wasn't able to find
an answer in the FAQs or help text.
Thanks!

Your main problem is that your boxes have zero thickness in the z
direction. That doesn't work very well in POV. Give them a little
thickness, like box{<-1,0,5> <9,8,5.25>}

The second problem is that the second component of your window
difference misses the first component completely. One has a z value of 5
and the other 2.5. Make the two boxes overlap, like this:
  difference{
    box {<-1,0,5> <9,8,5.25>}
    box {<2,3,4.5> <6,6,6>}

The third problem is that the "window" object isn't a window, it's a
wall with a window-shaped hole in it, so its texture shouldn't be Glass,
it should be your wall texture.

Then you need to get rid of the solid wall that's in the same place as
the wall with the hole in it.

But now there's no glass in the window, so you need to add something
like this

#declare pane = box{<2,3,5.1> <6,6,5.15> texture {Glass}}
object {pane}
