When the position of moving operation unit to control pointer model in virtual scene it is close to the structural model when,
Central processing unit can position of the end in real coordinate system described in real-time tracing, and calculate the end virtual point to knot
The nearest virtual point of structure model surface minimum distance, while the nearest virtual point being associated with into real coordinate system in reality
Corresponding nearest realistic is established in coordinate system, and then control force feedback unit moves, and the sphere is made to be moved to its lateral wall
The position that the closest approach of end apart from the operating unit is overlapped with the nearest realistic.
When referring to needle mould type touching structural model in virtual scene, that is, the end virtual point is moved to structure mould
When the surface of type, the sphere is touched in the end of the operating unit in real coordinate system, so that the sphere is to user one
A apparent force feedback.Meanwhile in virtual scene, the model of parts touched by pointer model changes render mode with table
Show that it is chosen, to further operating, as shown in Figure 10, the model of gear 100 therein is chosen；When the model of parts is by again
Render mode restores when primary touching, has been cancelled with indicating that it is selected.
After a certain components are chosen in virtual scene, can choose and carry out various operations to it, for example, by its with
Pointer model carries out locking and forms locking model, and as shown in figure 11, gear shaft model 200 and pointer model form locking model
The rending model of body, the two changes together, at this time when spatial position change when the end in real coordinate system, virtual
Described in scene locking model can be moved in the space of virtual coordinate system together with pointer model, while with gear Axle mould
The model of gear 100 that type 200 can link also moves together, as shown in figure 12.When gear shaft model 200 is relative to the model of gear
