Summary:A method for enabling to use an Image-Based Rendering (IBR) technology in Animation Framework extension (AFX) technology is provided. In the method for representing an object in a 3D scene using an IBR technology in the 3D scene, image information and depth information on each point of the image are used, or image information and a depth information array of all points projected on each point onto a plane of the image or a color information array of each point are used. In the method, by defining expression methods for GBT, LDI, and Octree that are simple method among IBR technologies having geometric information, those methods can be used in the MPEG-4 AFX.
