Unity3D下构件化虚拟仪器功能实现方法

Implementation of Virtual Instrument Based on Unity3D

三维虚拟现实漫游仿真和虚拟仪器实验过程仿真是目前两种主要仿真手段,前者能够很好地模拟真实实验场景,后者则能更好地仿真实验细节。为了解决传统虚拟实验交互性弱、开发周期长等问题,提出了一种Unity3D下的构件化虚拟仪器功能实现方法。首先在Unity3D平台上开发多种标准化、可复用的虚拟仪器;然后将虚拟仪器引入虚拟现实场景中,并通过基于事件中心的观察者模式实现虚拟仪器的通信和数据流动;最后,依据构建的虚拟仪器开展典型机械工程测量实验。结果表明,与传统虚拟实验相比,该方法具有更好的真实性、交互性,同时构件化的思想缩短了开发周期。

Three-dimensional virtual reality roaming simulation and virtual instrument experiment process simulation are two main simulation methods at present.The former can simulate the real experimental scene well,while the latter can better simulate the details of the experiment.In order to overcome the shortcomings of traditional virtual experiment such as weak interaction and long develop⁃ment time,this paper presents a method to realize the function of component-based virtual instrument in Unity3D based on virtual real⁃ity and virtual instrument technology.Firstly,a variety of standardized and reusable virtual instruments are developed on Unity3D plat⁃form.Then virtual instruments are introduced into virtual reality scene.The communication and data flow of virtual instruments are real⁃ized by observer mode based on event center.Finally,a typical mechanical engineering measurement experiment is built based on the virtual instrument.The results show that compared with traditional virtual experiment,this method has better authenticity and interac⁃tion,and the idea of component shortens the development cycle.
