Abstract

La présente invention concerne un procédé de projection sur grand écran, d'images synthétisées par ordinateur ainsi que le dispositif de mise en oeuvre. L'invention est remarquable en ce que le procédé consiste à inscrire les images en deux séquences successives, l'une par un balayage rapide de type télévision l'autre par un balayage aléatoire (ou calligraphique). Application : simulateur de vol.
