Abstract:
The requirements and features of virtual assembly movement
navigator are analyzed to help operators flexibly manipulate
virtual objects, precisely locate or assemble virtual parts in
virtual environment. With the degree-of-freedom analysis, the
assembly constraint hierarchical model is constructed and the
system’s constraints are built dynamically. Thus, all objects in
virtual environment can be located reasonally by the navigator.
Moreover, the assembly constraint recognition in the process of
assembly and movement correction is also discussed.
Key words:
Virtual assembly Movement navigation Degree of freedom
Assembly model Constraint recognition Movement correction
