Abstract

Method and device for processing a geometry image generated from a mesh associated with a 3D scene and comprising a plurality of charts that each represents a part of the 3D scene, the method comprising computing a reference direction (21) from mesh coordinates associated with a current pixel (203) and mesh coordinates associated with a first pixel (213), the first pixel (213) corresponding to a pixel of the border of the first chart located along a determined direction (20) having as origin the current pixel (203); comparing the reference direction (21) with a set of candidate directions (22, 23, 24, 25, 26) being each computed from the mesh coordinates associated with the at least one current pixel (203) and indirection mesh coordinates associated with one pixel (222 to 226; 212 to 214) of the neighbourhood of the first pixel (213), the indirection mesh coordinates corresponding to mesh coordinates of a pixel of the border a second chart corresponding to the pixel of the neighbourhood of the first pixel; and selecting a pixel of the border of the second chart according to the comparison result.
