A few days ago I discover the joy to make my own programming in Pov-Ray...
The scene bellow is used to create a tiled flood, it works very well but
when I want to makes it a "#macro" the things goes bad the macro doesn't
seem to work !
Here is....

The scene that works :

//  Persistence of Vision Raytracer V3.1
//  World definition file.
//
//  Creating tiled floors with a macro...
// Z coordinate = up

background { color <0.500,0.600,0.800> }

camera {  //  Camera StdCam
  location  <      0.000,     -15.000,      8.000>
  sky       <    0.00000,     0.00000,     1.00000> // Use right
handed-system
  up        <        0.0,         0.0,         1.0> // Where Z is up
  right     <    1.35836,         0.0,         0.0> // Right Vector is
adjusted to compensate for spherical (Moray) vs. planar (POV-Ray) aspect
ratio

Alright let me tell you what's going on.  :o)  First of all, none of the two
scene files work as you intended. The first one doesn't parse because you
didn't end the macro with #end and you didn't initialize the macro. The
second scene file works but doesn't make the floor because you forgot to
activate the object "carrelage" after having the macro create it. So add
this after having called the macro:

object { carrelage }

Hugo
