Selective scene transfer in Web applications

Applications like cooperative CAD and virtual touring on Web need to transfer a scene consisting of models and textures from one computer to another. However, the scene may be very large, and the time to transfer the whole scene is significant. During transferring, the user has to wait until the whole scene is downloaded to the local machine. We propose a new approach to estimate the visual importance of each object or even each polygon and a method that selectively transfer the models and textures in the scene. In this way, we can reduce user-waiting time while keeping the image quality the user can see.
