Abstract

L'invention concerne des techniques pour gérer une interaction avec un nuage de points fusionnés représentant un environnement numérisé. Le procédé est mis en œuvre par un contrôleur. Le procédé consiste à afficher le nuage de points fusionné. Le nuage de points fusionné est composé d'une union de nuages de points individuels. Tous les nuages de points individuels sont fournis dans un système de coordonnées commun. Le procédé consiste à obtenir une entrée pour une interaction avec le nuage de points fusionné. Le procédé consiste à sélectionner, en réponse au fait que l'interaction est associée uniquement à un segment du nuage de points fusionné, le nuage de points individuel ayant la densité de points de données la plus élevée de tous les nuages de points individuels dans un sous-cube correspondant au segment du nuage de points fusionné. Le procédé consiste à afficher le nuage de points individuel sélectionné au lieu du nuage de points fusionné.
