REMOTEVIS: REMOTE VISUALIZATION OF MASSIVE VIRTUAL ENVIRONMENTS
Soumyajit Deb, P. J. Narayanan · 2004
Graphics models for virtual environments are increas-ingly getting massive, requiring large amounts of mem-ory to store and high end graphics capabilities to ren-der. It may not be possible or desirable to store the entire model in the station where it will be rendered, especially for environments that change. Such virtual models could be stored on a server and streamed to remote clients on demand. In this paper, we present the design and implementation of a client-server sys-tem to render large virtual environments. Our sys-tem can provide the best visualization quality for a wide range in connection bandwidth and latency and the rendering capacity of the client. The system uses a visibility-based geometry representation so that lit-tle invisible geometry is sent to the client. Incremen-tal updating and client-side prediction of user motion optimize the communication requiremnts for a given client. We present results of the study conducted on a representative range of the relevant parameters in this paper. I.
