Hi,

The code is not that big.
I wrote a kind of script to animate the parts:

1) declared each basic part in a macro
2) wrote a file that shows which parts are shown and how long and how they move
and their appearance.
3) used a Borland Pascal 7 program to assemble and insert file for each frame.
This program was called once for every frame with the name of the object ( like
"piston" or "conrod" ) and the frame number.

The animation runs at 30 FPS for 6 min and 4 sec. A total of 10920 frames.

It took weeks to run on a 2001 PC using and older version of Povray.
I just left it running when I was sleeping or away for the weekend. Luckily
Povray does not crash!
