| Virtual Reality is a computer simulation system that can create and experience the virtual world.It uses computer to generate a simulation environment that allows users to immerse themselves into the environment.In modern science and technology,virtual reality has an important development prospect and application value.With the rapid development of virtual reality technology,a variety of virtual simulation applications emerge as the times require,and the virtual reality technology simulation training system has unique immersion,interaction and imagination.In order to make the primary and secondary school students and ordinary people rescue and escape by themselves when the fi re occurs,and to protect people’s lives and property safety,it is necessary to simulate the fire process of escape drill effectively and truly.This paper researches the key technologies of virtual simulation system of fire escape drill base on the Virtual Reality Technology.A virtual simulation system of fire escape drill is realized by using the advanced Unreal Engine 4(UE4);the fire,the explosion and the change of the flame’s color effects are realized by taking advantage of the particle system,to get JPEG images from external directly as textures for the flame particle system by C++programming with VS2015;the routing algorithm in traditional fire scene is improved to make the escape route more secure.The running results show that the simulate system developed with UE4 has strong immersion by vivid pictures,and the system provides a basic platform for further research on virtual simulate of fire escape drill. |
