Design And Implementation Of Interactive System For Virtual Reality Scene

Virtual Reality(VR)is an emerging technology that is widely used both at home and abroad and produces incalculable value.In the current trend of virtual reality research upsurge,virtual reality technology has gradually infiltrated into the field of teaching games.The combination of educational games and virtual reality is increasingly becoming a popular way.In this thesis a fire teaching system based on virtual reality technology has been developed.The system builds a virtual three-dimensional fire scene through computer,and the experiencer can conduct human-computer interaction in the virtual fire scene through the virtual reality equipment.The system provides fire equipment teaching functions,fire simulation exercises on the site,playback evaluation function of the three modules.By using the virtual reality technology to simulate the use of fire protection facilities,a virtual fire scene similar to the real fire is constructed.The entire fire drill process is simulated through human-computer interaction in the virtual scene so that experiencers can learn fire-related knowledge through a virtual fire experience and a system-designed playback evaluation function.In this thesis,fire-fighting teaching system,for example,combined with virtual display technology and software development technology is described in the virtual reality system design and implementation process.The core technical issues are deeply studied,such as the compatibility of virtual reality technology and fire-fighting teaching system,the realization of the system function module,the screen display and display efficiency and so on.The combination of fire teaching and virtual reality technology can solve the defects in the traditional teaching conditions,reasonably avoid the possible danger in the real operation process,break the limitation of space and time.Through the combination with virtual reality technology,there will be greater innovation in the field of fire protection teaching as well as broadening the application of virtual reality technology and promoting the development of virtual reality technology.My work has important practical significance.
