Abstract�� 3D models have been widely used on internet. However, the conventional publishing way which downloads models first and then renders has always been haunted by the limitation of security threat, network bandwidth and low graphic performance of client machines. By combining 3D model simplification and remote rendering technology, a new 3D model publishing system was put forward. The high-resolution models were kept on the rendering server. On the 3D viewer client only low-resolution versions of the 3D models were provided. User can zoom, translate and rotate the low-resolution model on the 3D viewer client. When user stops manipulating, the client sends a rendering request to the rendering server which includes the user’s current viewpoint, direction and lighting information. The rendering server then renders and returns images of high-resolution models according to client requests. This system can effectively guarantee the security of the 3D model and significantly lower the requirements for client machine’s graphical performance and network bandwidth.
