It is proposed a computer-implemented method for compressing a three-dimensional modeled object. The method comprises: - providing (S10) a mesh of the three-dimensional modeled object; - parameterizing (u,v) the mesh in a two-dimensional plane, the parameterization of the mesh resulting in a set of vertices having two-dimensional coordinates; - providing a grid on the two-dimensional plane; and - modifying the two-dimensional coordinates of each vertex by assigning one vertex to one intersection of the grid. Such compression method is lossless, completely reversible, suitable to efficiently reduce the storage size of a CAD file. |
