Interactive 3D content on the Internet has yet become popular due to its typically large volume and the limited network bandwidth. Progressive content transmission, or 3D streaming, thus is necessary for real-time content interactions. However, the heavy data and processing requirements of 3D streaming challenge the scalability of client-server-based delivery methods. We propose the use of peer-to-peer (P2P) networks for 3D streaming and argue that due to the non-linear access pattern of 3D content, P2P 3D streaming is a new class of applications apart from existing P2P media streaming. We also describe FLoD, the first P2P framework that allows clients in 3D virtual globe or virtual environment (VE) applications to obtain relevant data from other clients while minimizing server resource usage. To demonstrate how FLoD applies to real-world scenarios, a prototype system is built to adapt JPEG 2000 geometry image-based streaming for the P2P delivery of 3D scenes. Experiments show that server-side bandwidth can be conserved with P2P streaming, while simulations indicate that P2P 3D streaming is fundamentally more scalable than client-server approaches.
