【摘要】：虚拟现实(VR)技术是时下最流行最受关注的前沿科技之一,VR技术也称灵境技术或人工环境,其是集合仿真技术、计算机图形学、人机接口技术、多媒体技术传感技术以及网络技术等多种领域技术而开发的一种计算机仿真系统,能够创建并让用户感受到原本只有在真实世界才会拥有的体验。本文主要是研究虚拟现实技术应用3D虚拟校园的构建,为用户创建一个可以足不出户就可以了解校园的地理信息与文化背景的虚拟平台,并在此基础上扩展了校园常用的业务功能:用户只需通过鼠标既可了解每幢建筑物的房间分布情况,每间教室的座位数、状态信息,同时实现了进入教室,查看布局、课表查询、预约教室等功能。虚拟校园平台的构建既有助于提升学校形象,扩大学校声望,为学校提供一个更好的宣传展示的平台,也可以为用户提供一个更为开放的信息共享平台。本文主要使用HTML5和Threejs技术来实现虚拟校园场景的构建,使用3D Max建模软件为虚拟校园制作出3D模型,通过格式的转换,加载到Threejs构建的场景中,然后再为虚拟校园添加了多种交互功能,以便更好的展现学校的地理与文化背景。本文为了使用户有更好的体验,设计了两种虚拟校园漫游的模式,一种是使用鼠标对虚拟校园场景进行旋转、平移和缩放,给用户一个可以掌控虚拟校园全局的视角,另一种则是控制机器人行走在虚拟校园场景中,让用户通过机器人的视角浏览虚拟校园的每一处风景。构建好虚拟场景,实现基础功能以后,再为虚拟校园扩展业务功能,提供数据接口,丰富虚拟校园的功能,提高实用性。使用HTML5和Threejs技术构建的虚拟校园具有更好的兼容性、稳定性、画面渲染速度快,且具有非常棒的跨平台特性。电脑、平板、手机,只要拥有支持HTML5的浏览器即可访问虚拟校园。
[Abstract]:Virtual reality (VR) technology is one of the most popular and paid attention to the frontier science and technology. It is also called spiritual environment or artificial environment. It is set simulation technology, computer graphics, man-machine interface technology. A computer simulation system, which is developed by multimedia technology, sensor technology and network technology, can create and make users feel the experience that they only have in the real world. This paper mainly studies the construction of 3D virtual campus based on virtual reality technology, and creates a virtual platform for users to understand the geographical information and cultural background of campus without leaving home. On this basis, the common business functions of the campus are expanded: the user can not only understand the room distribution of each building, the number of seats and the status information of each classroom, but also realize the access to the classroom and view the layout. Schedule inquiry, reservation of classroom and other functions. The construction of virtual campus platform can not only promote the image of the school, expand the reputation of the school, provide a better platform for publicity and display for the school, but also provide a more open information sharing platform for users. This article mainly uses HTML5 and Threejs technology to realize the virtual campus scene construction, uses 3D Max modeling software to create the 3D model for the virtual campus, through the format transformation, loads into the Threejs construction scene, Then we add a variety of interactive functions to the virtual campus in order to better show the geographical and cultural background of the school. In order to give users a better experience, this paper designs two kinds of virtual campus roaming modes. One is to use the mouse to rotate, translate and scale the virtual campus scene, giving the user a view to control the overall situation of the virtual campus. The other is to control the robot to walk in the virtual campus scene, allowing users to view every scene of the virtual campus from the perspective of the robot. After constructing the virtual scene and realizing the basic function, we can expand the business function, provide the data interface, enrich the function of the virtual campus and improve the practicability. The virtual campus built with HTML5 and Threejs technology has better compatibility, stability, fast rendering speed, and excellent cross-platform features. Computers, tablets, mobile phones, as long as you have a browser supporting HTML5 can access the virtual campus.
