3D Script : Blender - Render in Background

Voici un script que j'ai fait pour Blender qui permet de lancer des rendus en arrière plan.
Il utilise le gnome-terminal pour rendre une image ou une animation.
Ceci permet de :

• continuer à travailler sur Blender lorsque l'on fait ses rendus.
• faire des rendus plus rapidement (ça 'devrait' aller plus rapidement, je n'ai pas fait de test...)
• ne pas se prendre la tête et à chercher sur le net pour savoir les commandes et les arguments à mettre dans la console pour lancer un rendu en arrière plan (c'est pourquoi j'ai fait ce script)

Blender peut-être fermé, du moment que le gnome-terminal reste ouvert, le rendu continuera.
Donc pour cette version du script, le gnome-terminal doit être installé.
Je n'ai testé ce script que sur Ubuntu 8.10 Intrepid Ibex 64 bits, je ne sais absolument pas s'il marchera sur d'autres OS.
(Séléctionnez le script et 'ctrl+c' pour copier le script)

This is a script made for Blender. It opens a the gnome-terminal for render an image or an animation in background.
This allow you to :
    - continue work in Blender when you render.
    - rendering more fast (it should rendering more fast, i didn't do any test...)
    - don't think and search the commands and arguments to put in the terminal for launch a render in background (it why i made that script)
 
Blender can be closed, since the gnome-terminal is still open the render will continue.
So for this version of this script, gnome-terminal must be installed.
The script work on my Ubuntu Intrepid Ibex 64 bits, i don't know at all if it will work on other OS.
(select the script and make ctrl+c for copy it)

Can you help me make it work on any terminal ?
 
The script work on my Ubuntu Intrepid Ibex 64 bits, i don't know at all if it will work on other os.
Can you help me make it work on any os ?
 
If your can improve it, dont hesitate.
 
To do :
 - Universal terminal
 - Make it work on all OS
 - Auto-center gui
