Abstract

La présente invention concerne un système et un procédé de modélisation tridimensionnelle automatique permettant la génération d'un modèle tridimensionnel à partir d'une image ou analogue. Par exemple, il permet la génération automatique d'un modèle tridimensionnel pour le visage d'une personne. Le système et le procédé permettent également la génération automatique de gestes/comportements associés à un modèle tridimensionnel de sorte les gestes/comportements soient applicables à d'autres modèles tridimensionnels quelconques.
