Abstract

The standard way of remotely visualizing virtual worlds is downloading the virtual world to the user´s computer, then rendering it. This approach is plagued by many problems which can be overcome by moving the rendering at server´s side and by essentially turning interactive visualization into an image transmission problem. How to effectively compress the rendered views which need to be transmitted to the client is a fundamental issue within this remote visualization scenario. This work presents an original compression scheme for remote visualization based on image based rendering. A remote visualization system incorporating this compression method was implemented and its experimental performance is discussed.
