Three-dimensional (3D) graphical model is about to become a full-fledged multimedia data type, prompted by increasing popularity of Virtual Reality Modeling Language (VRML) [7] and imminent standardization of MPEG4 [8].
Following an introduction on data embedding, this paper presents a discussion on potential targets of data embedding that exist in both VRML and MPEG4 formats. We then present several algorithms that embed data in shape (i.e., geometry and topology of the shapes) and shape attributes associated with shape (e.g., per-vertex texture coordinates).
