> For example:

Wouldnt it be better to combine polygons?

My solution:


#macro BoxTex(A,B, Af,Aw,Ac)
  union {
    polygon { 4
      <A.x,A.y,A.z> <B.x,A.y,A.z>
      <B.x,A.y,B.z> <A.x,A.y,B.z>
      texture { Af rotate x*90 }
    }
    
    polygon { 4
      <A.x,A.y,A.z> <B.x,A.y,A.z>
      <B.x,B.y,A.z> <A.x,B.y,A.z>
      texture { Aw rotate z*90 }
    }
    polygon { 4
      <A.x,A.y,B.z> <B.x,A.y,B.z>
      <B.x,B.y,B.z> <A.x,B.y,B.z>
      texture { Aw rotate z*90 }
    }
    
    polygon { 4
      <A.x,A.y,A.z> <A.x,B.y,A.z>
      <A.x,B.y,B.z> <A.x,A.y,B.z>
      texture { Aw rotate y*90 }
    } 
    polygon { 4
      <B.x,A.y,A.z> <B.x,B.y,A.z>
      <B.x,B.y,B.z> <B.x,A.y,B.z>
      texture { Aw rotate y*90 }
    }
    
    polygon { 4
      <A.x,B.y,A.z> <B.x,B.y,A.z>
      <B.x,B.y,B.z> <A.x,B.y,B.z>
      texture { Ac rotate x*90 }
    //  scale 0.10
    }
  }  
#end

Call it usign two vectors, and three textures - for floor, walls and 
celing.

It is neede to:
  A.x < B.x
  A.y < B.y
  A.z < B.z

btw, povray complains about not closed polygon, how to fix it (just add 5-
th point?)
