Vpython
la puissance de Vpython
Ceci est un exemple de programme qui utilise le module d'extension Vpython
( http://www.vpython.org/ ).Le site contient un tutorial et l'installation est intuitive.
Voici un exemple d'agents (fourmis) qui évoluent
dans un environnement: le but n'est pas de surcharger le code d'intelligence artificielle distribuée (IAD)
mais de vous montrer la rapidité avec laquelle on peut effectuer une représentation 3D d'un système multiAgent avec VPython.
