MPEG-4 LASeR as a standard was established for expressing rich media within a mobile environment. It is difficult to describe 3D nodes of MPEG-4BIFS, however, because LASeR can view only 2D graphics. To play MPEG-4 3D scenes within a mobile environment, this study demonstrated a method of creating 3D nodes with LASeR. First, the values of the attributes of BIFS 3D graphic nodes were calculated. Their 3D coordinates were converted into 2D coordinates, and then coordinate transformation was applied. At the close of the play, 3D scenes were created through LASeR 2D graphic nodes using 2D coordinate values. This made it possible to play MPEG-4 3D geometry objects within a mobile environment.
