Abstract
A depth image-based representation (DIBR) method of modeling a 3-dimensional (3D) object, by which the 3D object is expressed by depth information, color information, and camera parameters or geometry information, color information, and camera parameters. The camera parameters include position, orientation, ranges of camera view or angle (fieldOfView), front and back of a camera volume (nearPlane and farPlane) and projection information(orthographic) on whether an object is projected on a camera orthographically or perspectively, and, when at least one of modeling and rendering of a 3D object is performed, values of the camera parameters are changed in real time.
