| Tóm tắt: | Virtual Reality-based surgical simulators can utilize Collaborative Virtual
Environments (C-VEs) to provide team-based training. To support real-time
interactions, C-VEs are typically replicated on each user’s local computer and a
synchronization method helps keep all local copies consistent. This approach does
not work well for voxel-based C-VEs since large and frequent volumetric updates
make synchronization difficult. This paper describes a method that allows multiple
users to interact within a voxel-based C-VE for a craniotomy simulator being developed.
Our C-VE method requires smaller update sizes and provides faster synchronization
update rates than volumetric-based methods [1,2]. Additionally, we
address network bandwidth/latency issues to simulate networked haptic and bone
drilling tool interactions with a voxel-based skull C-VE |
