  - Mio 'Rail Track System',
    un sistema di binari
    per POV-Ray
    Elementi di base dei binari
    - Binari diritti e curvi
    - Scambi o deviatoi
    - Scambi Y e a 3 vie
    - Incroci

    - Uso semplificato con
      RT_System_00.inc
      - Gli elementi binari
        di RT_System_00.inc

    - Binari adattati alle
      scale di fermodellismo
      - Binari in scala H0
      - Binari in scala N
      - Binari in scala Z

    - Piani Binari con
      binari adattati
      - Posa dei binari
      - Binari su e giù

Example 2 : Otto semplice con ponte
 (Sistema di binari a scala N, geometria tipo A)

Per binari curvi abbiamo spesso bisogno di ruotare binari con un angolo intorno
un centro di rotazione usando la macro 'Rotate_Around_Trans( RotationVector, Center_of_Rotation )'
dal include file 'transforms.inc'.
Possiamo sostituire questo comando molto lungo
'Rotate_Around_Trans(<0, 1*15,0>,<0,0,-R1>)'
con una espressione come 'RTyz( 1*15, -R1 )'
con dichiare la macro seguente: 
//----------------------------------------------------//
#include "transforms.inc"
#macro RTyz( Y_Angle, Z_Distance )
 Rotate_Around_Trans(<0, Y_Angle,0>,<0,0, Z_Distance>)
#end
