The invention concerns the refinement of a triangular mesh representing a
three-dimensional object (3D), said mesh consisting of an arrangement of
vertices and triangular surfaces, each defined by three references to the
vertices which it links, and having three edges each linking two of said
vertices. The invention is characterized in that said method comprises a
step which consists in selecting at least a region of interest, said mesh
refinement being carried out locally on at least one region of interest.
