The Construction Of Anti-Terrorism Aid System Based On VRML Scene

Virtual reality technology is a comprehensive utilization of computer graphics, sensortechnology, multimedia technology, man-machine interface technology and many kinds oftechnologies, Through the use of hardware, such as computer, all kinds of display andcontrol equipment, it generates a integration of immersing，interactive, realistic sight,hearing and touch of3d virtual environment.Rescue problem is a basic requirement for anti-terrorism. Anti-terrorism aid systembased on the scene model in the computer environment, use virtual reality technology tosimulate the true scene of terror, according to the scene, trainees or commander can makerescue plan or scheme, efficiently use the city’s related department of rescue resources,improve emergency response capacity. This system also is applicable to fire control,battlefield rescue.This paper’s innovation points as follows: Anti-terrorism aid field model is rapidlyestablished using VRML3D imaging technology, which makes the anti-terrorism field3Dvisual and clear, changes the traditional two-dimensional or coordinate field modelingmethod, makes decisions quickly and accurately and improves the effect of the rescue;Data modeling tool subset method is studied, which makes the scene modeling fast andaccurate, including for characters, architecture, landscape, equipment of rapid modeling;This rescue scene information based on the network can be distributed to the internet, suchas command post model, on-site rescue scene model of network publishing; This paperuses the organic combination of virtual reality technology and simulation technology,especially studies the database interaction technology and database interface technology,and improves the algorithm research.
