  Have you ever heard of #while-loops? They are handy, you know...


#declare GrassPatch = mesh { ... }

#declare Xpos = 0;
#while(Xpos < 100)
  #declare Zpos = 0;
  #while(Zpos < 100)
    object { GrassPatch translate <Xpos, 0, Zpos> }
    #declare Zpos = Zpos+1;
  #end
  #declare Xpos = Xpos+1;
#end

  Magically you get 100*100 instances of the mesh.
