摘要：    虚拟现实(Virtual Reality，简称VR)技术，是上个世纪末期兴起的一门多学科综合技术。借助于虚拟现实技术来帮助人们对一些特定的危险场景进行模拟演练，已经成为虚拟现实技术研究的热门方向之一。本文以楼道火场逃生为出发点,主要基于Unity3D引擎创造一个仿真的三文虚拟环境，人们可以身临其境的体验完全仿真的虚拟火场逃生环境。使用户有沉浸感，并在其中学习到正确的火场逃生方法,而不必再采用真正点火的方法进行类似实验。减少类似真实场景演练需要的场地和时间成本。全文分四个部分，第一部分简要介绍火灾的影响以及进行虚拟火灾演示的必要性，另外还介绍虚拟现实技术的特点及应用，简单介绍下虚拟技术的未来发展；第二部分是分析并比较虚拟楼道场景建模和场景演示过程中需要使用的方法和软件，为进行场景建模和演示制作提供理论依据和技术支持；第三部分具体介绍场景模型的建立以及场景演示特效的完成，完整的提出整体演示的制作过程和方法，最后是结论。22926

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.
