Abstract

a. Dispositif de mise en perspective d'objets tridimensionnels b. Il comprend un appareil d'acquisition de coordonnées tridimensionnelles définissant lesdits objets, des moyens d'enregistrer et de restituer ces coordonnées, un appareil de visualisation de la perspective et un dispositif calculateur de perspective, caractérisé en ce que ledit dispositif calculateur de perspective comprend trois changeurs de coordonnées transformant les coordonnées tridimensionnelles d'un point donné de l'objet en coordonnées bidimensionnelles d'un point du plan de visualisation de la perspective, ce dit point du plan de visualisation étant aligné avec ledit point de donné de l'objet par rapport à l'oeil de observateur, et des moyens d'appliquer audit appareil de visualisation des signaux représentatifs de ces coordonnées bidimensionnelles. c. Visualisation de perspectives d'objets tridimensionnels.
