Abstract

Cette invention se rapporte à un procédée grâce auquel un système client et un système serveur peuvent coopérer pour restituer des vues d'un monde virtuel dans lequel navigue un utilisateur du sytème client. Le serveur envoie au système client une vue de référence et un modèle servant à extrapoler la vue de référence en réponse au mouvement virtuel de l'utilisateur. Le système client envoie au serveur un enregistrement du mouvement virtuel de l'utilisateur. Le système client et le système serveur effectuent tous les deux l'extrapolation de la vue de référence sur la base du modèle. Le serveur effectue également une mise à jour exacte de la vue de référence. Lorsque la vue de référence extrapolée s'écarte trop de la vue de référence mise à jour, le serveur envoie au système client la différence entre la vue de référence extrapolée et la vue de référence mise à jour, pour que le client puisse mettre à jour sa vue de référence.
