Large-volume 3D triangle mesh model has large difficult to render, store, and transmit in Internet. This research investigates a 3D (3-dimension) streaming technology to overcome the difficulties in model transmission over Web. Edge collapse based mesh simplification and progressive mesh refinement are studied, which is crucial to establish 3D streaming technology. A prototype with GUI for mesh simplification and refinement and peer-to-peer network architecture are developed to implement the 3D streaming technology for Internet-enabled transmission of 3D mesh model.
