In the process of optoelectronic theodolite real-time interactive simulation,the high frame virtual image distortion can t be avoided because of the limit of hardware process capability.

Based on the related parameter transformation from virtual image to virtual sound environment,the integration of virtual image and virtual sound field was investigated in this paper.

Research on the Virtual View Maintenance of Information Grid;

In order to share data among the heterogeneous databases,gives a system architecture of heterogeneous database platform based on virtual view.

The application of virtual reality technology and internet technology makes the idea of building cyberspace in virtual map become possible.
