Annotation and View Synchronization of Shared 3D Models

Many pictures and videos have been shared on the Web. Thus, it is easy to find what one needs by using a Web search engine. Given the popularity of 3D printers, it is expected that 3D models will also be shared in the same manner. We focus here on 3D models with camera viewpoint and propose a prototype implementation of the annotation sharing system of 3D models. We also implement the synchronization mechanism for 3D models based on Publish/Subscribe model. Then, we evaluate the resource overhead of a server and the response time of clients in our prototype.
