| 中轴线城门历史文化虚拟交互展示
摘要
如今科技技术发展迅猛，虚拟交互方式也得到了飞跃性的发展，并且虚拟3D交互技术也被运用到了各种场景方式之中，沉浸式的交互体验不仅能让体验者以更身临其境的方式感受某些场景和事物，也可以以日常生活中不能做到的角度探索其中的奥妙。
北京中轴线历史文化遗产丰富，正在申报世界文化遗产，作为北京老城严谨对称空间格局的核心，蕴含着元、明、清及现代中国首都城市在城市规划方面的独特匠心[13]。论文主要研究内容是利用数字化的方式对北京中轴线历史城门的可视化建模、多视角用户交互体验方法。
论文利用unity 3D游戏引擎设计并开发了中轴线城门可视化交互系统。利用三维建模可视化、虚拟漫游和体验交互方式展示中轴线城门历史、文化。使用Unity3D引擎，搭建北京中轴线虚拟场景，使用第一人称漫游触发，实现场景跳转，多视角浏览、旋转缩放模型，利用图文等多媒体信息展示中轴线悠久的历史文化。
Abstract
Nowadays, science and technology are developing rapidly,Virtual interaction mode has also been a leap forward development,And virtual 3D interactive technology has alsobeen applied to a variety of scenes,Immersive interactive experience can not only make the experiencer feel some scenes and things in a more immersive way,we can also explore the mystery from the angle that we can't do in our daily life.
Beijing central axis is rich in historical and cultural heritage.As the core of the rigorous and symmetrical spatial pattern of Beijing's old city,it contains the unique ingenuity of Yuan, Ming, Qing and modern Chinese capital cities in urban planning.The main research contents of this paper are the visualization modeling and multi perspective userinteraction experience method of Beijing central axis historical city gate by digital way.
n this paper, the visual interaction system of the central axis city gate is designed and developed by using unity 3D game engine. The history and culture of the central axis gate are displayed by three-dimensional modeling visualization, virtual roaming and experience interaction. The unity3d engine is used to build the virtual scene of Beijing central axis,and the first person roaming trigger is used to realize scene jump,multi view browsing, rotating and zooming model,and multimedia information such as graphics and text is used to display the long history and culture of Beijing central axis.
