Abstract

La présente invention concerne comprend : une unité de stockage de modèles tridimensionnels servant à stocker un ensemble de données de modèle tridimensionnel ; une unité de stockage de gamme de points de vue servant à stocker la gamme de points de vue dans laquelle l'axe de rotation disposé sur un modèle tridimensionnel sert de référence ; une unité de génération servant à générer une première image qui est une image de projection bidimensionnelle obtenue d'après les données de modèle tridimensionnel sur la base d'une première position de point de vue à l'intérieur de la gamme de points de vue ; et une unité de réception de commande de modification servant à recevoir une commande afin de modifier la position du point de vue d'un utilisateur. L'unité de génération modifie la position du point de vue à l'intérieur de la gamme de points de vue selon la commande de modification, et génère une deuxième image qui est une image de projection bidimensionnelle dans laquelle le modèle tridimensionnel dans la première image est tourné autour de l'axe de rotation sur la base de la position du point de vue après la modification. Une première unité de sortie sort la deuxième image.
