La technologie
La simulation visuelle exploite pleinement les caractéristiques visuelles humaines et crée un environnement graphique tridimensionnel qui reflète les changements et les interactions des entités grâce au rendu en temps réel des graphiques tridimensionnels, afin d'obtenir un effet de simulation très réaliste.
