Real-time selective scene transfer

Applications like cooperative CAD and virtual touring on the Web need to transfer a scene consisting of models and textures from one computer to another. The scene may be very large, and the Lime 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 of each polygon and a method that will 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.
