Process for managing the representation of at least one 3D model of a scene

摘要

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 modelling 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.
