Abstract

Le système décrit permet de donner une rétroaction à deux participants dans un studio virtuel. Une image est rendue du point de vue du participant concerné et projetée de sorte qu'elle soit visible pour le participant tout en étant découpée de l'image de la caméra du studio par un procédé d'incrustation.
