I have created a paper on PovRay and have mapped a scanned newspaper onto
it. Now, the scanned newpaper appears on both sides on the newspaper.
Oneside is what I want and the other side is in reverse. I'd like to keep
the other side blank AND/OR and different image map on the other side. Can
anyone guide me to the two different possibilities?

#declare Box=box{<0,0,1>,<4,4,0>
 texture {pigment{image_map { tga "Image.tga"
 map_type 0 interpolate 2} }
 scale<2,4,1> }}

#declare Box2=box{<0,0,0>,<2,10,.1>
 texture {pigment{image_map { tga "Image2.tga"
 map_type 0 interpolate 2} }
 scale<2,4,1> }}

// white back side of paper
#declare Pg=intersection{
 object{Box}
 box{<0,0,0>,<2,10,.1> pigment{White}}
}

// Image2 on back side of paper
#declare Pg=intersection{
 object{Box}
 object{Box2}
}
 

You can also use the Height_field this way too.
Late but, Hope this helps.
