Research on the acquisition and expression of virtual interactive features

Virtual reality technology is a new way for people to visualize and interact with complex data through computers. Virtual reality technology based on simulation software is relatively mature. However, the simulation process is more complicated and the simulation of the interactivity cannot be satisfactory. Immersive virtual objects in the virtual scene are more interactive, and more in line with the laws of physics, and more consistent with the real world. The interactive features of virtual maintenance objects are expressed in a variety of ways. It uses modeling and provides constraint method to express the inherent attribute, object such as size, color, geometry. At the same time, we use software to correct the picture of the separation and the non-synchronization caused by the vertical relationship between screens. This paper uses a variety of techniques to achieve the acquisition and expression of virtual interactive features.
