Abstract

See full text

A method is provided for designing a 3D modeled object comprising the steps of providing at least one surface defined by a field of points of the surface and a field of normal vectors normal to the surface; and watermarking the object by modifying the field of points while keeping the field of normal vectors as it is. Such a method provides a technique for tracing a 3D modeled object modeled at least by a field of points of a surface and a field of normal vectors normal to the surface.
