Joint Geometry/Texture Progressive Coding of 3D Models

Files of 3D models are often large and time-consuming to download. Most 3D viewers need the entire file to display a 3D model even when the user is interested only in a part of or a low-resolution version of the model. Therefore, progressive coding of 3D models is desired. However, existing work studies either the progressive coding of the geometry only, or progressive coding of the texture only. In this paper, we propose a joint geometry/texture coding technique for 3D objects. Both of the geometry and the texture are progressively coded and transmitted to the viewer. The most perceptually important bits are sent before the less important bits, allowing the users to stop the download at any time and yet retain the best quality available at that time.
