We have developed a novel volume-based haptic collaborative virtual environment system, which allows participants at remote sites on the network to simultaneously interact with the same target object in virtual environments, by only exchanging a small set of manipulation parameters for the target object. We first developed an online-remesh volume model, we call dynamic adaptive grids, for simulating deformable objects such as soft tissues in each remote site. Then haptic sensation during interaction with the target object, is achieved by rendering the reflection force from the object, simulated with the online-remesh volume model from the manipulation parameters exchanged among all remote sites. This time, we improved the synchronization precision of the system
