CA 2209275

A method for dynamically generating synthetic images using Delaunay gridding, wherein only those terrain portions in which a significant level-of-detail variation occurs are processed in real time, said significant variation being determined on the basis of the angular error that would be made, from the observer's viewpoint and relative to the various points of the terrain, if these points were not processed. Only an angular error above a given threshold is taken into account.

Le procédé de génération dynamique d'images synthétiques de l'invention fait appel au maillage de Delaunay, et seules sont traitées, en temps réel, les portions de terrain pour lesquelles une variation significative du niveau de détail a lieu, cette variation significative étant déterminée par l'erreur angulaire, du point de vue de l'observateur, et relative aux différents points du terrain, que l'on commettrait si l'on omettait de traiter ces points, seule l'erreur angulaire supérieure à un certain seuil étant prise en compte
