Hello Peter, Chris, Ken and Mr. Art:

I have made and will try out the following files:

1. X.POV ====================================== :

object {KOL(M000) translate < x000, 0, z000 > }
object {KOL(M001) translate < x001, 0, z001 > }
-
-
-
object {KOL(M999) translate < x999, 0, z999 > }


2. Y.INC ====================================== :

#macro KOL(TT)
#declare COLUMNA =
union

  cylinder { <0, 0, 0>,<0, 5.47, 0>, 29.79 texture{ myTexA } }
  object   { OBJECTA texture{ myTexB }  }
  cylinder { <0,14.55,0>, <0,400,0> ,22.5 texture{TT}}

  scale 2
}
COLUMNA
#end


3. Z.INC ======================================= :

#declare M000 = texture{MyMarble translate 0000}
#declare M001 = texture{MyMarble translate 0010}
-
-
-
#declare M999 = texture{MyMarble translate 9990}

===================================================

This works fine and doesn't seem to require very much memory, although I
admit that I only went as far as 100, not 1000 different textures and
columns. It looked great. The difficulty is having easy access to
constructing the KOL-object-lines and the Mxxx-texture-lines. I will use an
appropriate C-program.

You don't think there is a simpler way? Something with #whiles ?

Your comments would be greatly appreciated.

Sander
