ABSTRACT:
Process for managing the representation of at least one model of a scene including buildings intended to be transmitted to a client. The scene is modelled by a multi-scale tree-structured representation. Different nodes are associated with the different levels of details of the scene. These different nodes are dependent on each other in a tree structure in which at least one son node is defined by information known by a father node and by additional information in respect of the son node. A processing operation to simplify the representation is applied to the modelling and priorities for implementing the simplification processing operations are determined by a cost function which takes account of the criterion of the difference in height of the merged buildings.
