CA 2235089

In a search method and system for reducing the number of memory page-in/page-out operations to display, three dimensional objects are extracted through space search. The system comprises a parameter accepting module (22) which accepts parameters from a user to set up a view volume, a space searching module 24 which searches for an object which is included in the view volume, a tree holding module (28) which holds a multi-dimensional tree describing the three-dimensional coordinates of the object, and a file reading module (29) which loads the object data into memory in file units.

L'invention est constituée par un système et une méthode servant à réduire le nombre des chargements et des renvois de page à afficher, dans lesquels des objets tridimensionnels sont extraits à la suite d'une recherche spatiale. Le système de l'invention comprend un module d'acceptation de paramètres (22) qui accepte les paramètres introduits par un utilisateur pour établir un volume de vue, un module d'exploration spatiale (24) qui cherche les objets situés dans ce volume de vue, un module de stockage d'arbres (28) utilisé pour stocker un arbre multidimensionnel contenant les coordonnées tridimensionnelles des objets cherchés, et un module de lecture de fichiers (29) utilisé pour charger les données sur ces objets dans des fichiers de mémoire.
