Argh...sorry, It seems I had a bit of finger trouble...
What I meant was Pyramid from shapes2.inc - anyway heres what i'm using:
#declare Pyramid =
   mesh {   //changed from union
      triangle { <-1, 0, -1>, <+1, 0, -1>, <0, 1, 0>  }
      triangle { <+1, 0, -1>, <+1, 0, +1>, <0, 1, 0>  }
      triangle { <-1, 0, +1>, <+1, 0, +1>, <0, 1, 0>  }
      triangle { <-1, 0, +1>, <-1, 0, -1>, <0, 1, 0>  }

      triangle { <-1, 0, -1>, <-1, 0, +1>, <1, 0, +1>  }
      triangle { <-1, 0, -1>, <+1, 0, -1>, <1, 0, +1>  }

   scale <1, 2, 1>
   translate -y
}

I then have a loop which writes an include file by generating random
translations and rotations in the form:
object {Pyramid translate <...> rotate <...>}
object {Pyramid translate <...> rotate <...>}
object {Pyramid translate <...> rotate <...>} ...x60,000

although the .inc file isn't written on every render.
Is there a more effiecient way of writing this?

Thanks
Jim
