Abstract:
We present an effective method for sharing 3D models over the network, while supporting the same viewing environment and collaborative manipulation of 3D objects with applications to remote maintenance of industrial equipments. The 3D models are first presented in a top-down manner, which facilitates an intuitive understanding of their hierarchical structure. The kinematic structure is also presented so as to explain the moving mechanism of 3D models. Part assembly/disassembly is a basic procedure in part maintenance, which is shown in animation clips as well as in diagrams. To maintain the viewing environment consistent, we synchronize the result of model operations by sharing only a small number of state variables over the network. We don’t reply on a separate server or a lock/unlock mechanism for the synchronization. As a result, we support an efficient manipulation of complex 3D models shared over the network. The developed system provides an intuitive interface and demonstrates
an interactive performance.
