Although compression of 3D content has been a widely studied topic, adaptive streaming of large virtual scenes is progressively becoming the standard way to share collaborative environments, due to the growing complexity of the shared data. The classical 'download and play' paradigm associated to standalone compression is leaving place to interactive refinements of regions-of-interest, provided given polygon budget and network capability. With the increasing number of applications and potential clients sharing reusable data, the traditional client / server architecture is likely to be over passed by less server-centered protocols, in order to distribute the complex tasks of identifying the selected data to be streamed. In this paper, we present the design and performances of a platform exploiting peer-to-peer transmission and show how the whole setting can be implemented using the MPEG-4 AFX standards.
