Abstract

During COVID-19 pandemic, researchers have used innovative technologies for fast tracking the development to end this pandemic. Virtual Reality (VR) has offered an imperative role for fighting this pandemic, through audiovisual-based virtual communication. Virtual reality modeling language (VRML), as an international standard of virtual reality, has developed rapidly. VRML expanded the function of script node by introducing Java and script programs written in java script language. This paper presents a VRML method. Libraries and platoons are virtualized to meet the normal use of users. In principle, any text editing system can be used for VRML programming, but some editing systems have few related functions and are not suitable for large-scale VRML Scene Design. The VRML algorithm proposed in this paper can be applied to large buildings. The VRML algorithm proposed in this paper is compared with the traditional algorithm. The VRML algorithm proposed in this paper is superior to the traditional algorithm in the aspects of realism, interactivity, design rationality and execution speed. The practicability of the VRML algorithm is proved. It provides help for people who are inconvenient to go out during the protection period of covid-19.

虚拟现实建模语言技术在COVID-19大流行中的应用

摘要

在COVID-19大流行期间，研究人员使用创新技术快速跟踪了发展情况，以结束这种大流行。虚拟现实（VR）通过基于视听的虚拟通信，为应对这种流行病发挥了必不可少的作用。虚拟现实建模语言（VRML）作为虚拟现实的国际标准，发展迅速。VRML通过引入Java和用Java脚本语言编写的脚本程序扩展了脚本节点的功能。本文提出了一种VRML方法。图书馆和排被虚拟化以满足用户的正常使用。原则上，任何文本编辑系统都可以用于VRML编程，但是某些编辑系统的相关功能很少，因此不适用于大规模VRML场景设计。本文提出的VRML算法可以应用于大型建筑物。将本文提出的VRML算法与传统算法进行比较。本文提出的VRML算法在真实性，交互性，设计合理性和执行速度方面均优于传统算法。证明了VRML算法的实用性。它为在covid-19保护期间不方便出门的人提供帮助。
