Claim One:
1. A computer-implemented method for designing a 3D modeled object, the method comprising: defining, by a user, a base mesh associated to a subdivision surface and to a corresponding predetermined mesh-to-NURBS-surface conversion algorithm PCCM(⋅), the subdivision surface representing the 3D modeled object; defining, by the user, a 2D image and a location for engraving the 2D image on the subdivision surface; and determining a non-uniform rational basis spline (NURBS) surface S 1 that corresponds to applying a deformation map i,j Δ(i,j) on the result S 0 =PCCM(B 0 ) of performing the mesh-to-NURBS-surface conversion algorithm to the base mesh, the deformation map including displacement vectors provided for positions of the result of performing the mesh-to-NURBS-surface conversion algorithm to the base mesh, the positions corresponding to the location for engraving the 2D image, the displacement vectors being computed based on corresponding pixel values of the 2D image, wherein the corresponding pixel values of the 2D image are pixel grayscale values, and wherein the NURBS surface is determined based on magnitudes of the pixel grayscale values.
