This paper proposes an optimized virtual assembly relation model on the basis of deep analyses of traditional ones. Some typical adaptive virtual camera view modes are designed based on constraint conditions and dynamic data structure of optimized model mentioned above for a reversible virtual process of assembly and disassembly. These newly designed viewing modes are able to auto-adjust focus and field of view to follow and aid user operations by ensuring that camera view continuously focuses on virtual operating space currently in need, which lower the difficulty of user operations and heighten the efficiency of virtual operations.
