Patent ID: 7106328

Claim:
Process for managing the representation of at least one model of a scene including buildings intended to be transmitted by storage means to a client, said scene being modelled by a multi-scale tree-structured representation, in which different nodes are associated with the different levels of details of the scene, these different nodes being dependent on each other in a tree structure in which at least one son node is defined by informations known by a father node and by additional informations, the informations stored by the storage means in respect of the son node being these additional informations, characterised in that a processing operation to simplify the representation is applied to the at least one model of the scene and in that priorities for implementing the simplification processing operations are determined by determining a cost function which takes account of the criterion of the difference in height of the merged buildings, wherein the cost function determines the priorities of implementation of simplification processing operations additionally takes account of the following criteria: the difference in altitude of the merged buildings, the additional surface area generated by the merging, the minimum distance between the merged buildings.
