Abstract: The present invention concerns a method for adapting a mesh model to make it match a target. The model comprises a plurality of reference interfaces, each reference interface being associated with a target interface in the target. The method comprises, for at least one pair of successive interfaces, defining four intersections between a current alignment and the reference interfaces or the associated target interfaces, and modifying the coordinates for each current corner of the alignment on the basis of the initial coordinates of the current corner, and the four defined intersections, the modified coordinates of the current corner being on the current alignment.
