Virtual Corridor Fire Escape Scene Demo Based on Unity3D
Abstract: Virtual Reality (Virtual Reality referred to as VR) technology is a multidisciplinary and comprehensive technology rising in the late twentieth century. It has become one of the hottest virtual reality technology research direction to use virtual reality technology to help people to perform simulation exercises for certain dangerous scenarios. In this paper, fire escape corridor as a starting point primarily bases on Unity3D engine to create a three-dimensional virtual simulation environment. People can experience an immersive virtual fire escape and complete simulation environment, which gives users a sense of immersion and teaches them the correct method of fire escape, without having to adopt a real-ignition experiments to achieve such experiments. It reduces the costs of space and time compared to the real scene experiment. The paper is pided into four parts .The first section briefly introduces the effects of fire and the necessity of carrying out virtual fire demonstration. It also introduces the characteristics and applications of virtual reality technology, and introduces the development trend of virtual reality technology; The second section is to analyze and compare methods and software in virtual corridor scene modeling and scenario demonstration ,which provides the theoretical basis and technical support for scene modeling and demonstration production; The third section is to introduce the process of establishing scene model and the completion of demonstration scene’s effects, and put forward the process and methods of the whole demonstration production. The last section is the conclusion.
