摘要
为了改善电工电子虚拟实验教学效果和操作体验,提出一种基于开源软件OpenSceneGraph(OSG)开发的虚拟实验平台设计方案,该设计方案采用OSG开发三维视景,应用微软基础类(MFC)搭建程序框架,利用C++程序完成参数计算及控制操作的后台实验仿真。以几个典型虚拟实验为例,阐述了该设计方案的实现过程、系统构架以及元件模型搭建、虚拟环境构建、实验操作功能实现、实验现象模拟等主要技术要点。这种基于OSG的虚拟实验平台设计方案人机交互界面友好,实验环境丰富逼真,显示效果生动形象和有较强的灵活性与可操作性,为电工电子实验教学提供了新手段。
In order to improve the effect and operation experience in virtual electrical and electronic experiment education, a solution is put forward in this paper for virtual experiment platform design and development based on an open source software OpenSeeneGraph （OSG）. This solution involves 3D scene environment developed by OSG technology, application framework built by MFC and background experiment simulation system, based on C ＋＋ , which is responsible for parameter calculating and program controlling. By taking some representative virtual experiments for example, the development process, the system structure and the main technology characteristics of the virtual experiment platform, such as device model, virtual scene environment, experiment manipulation and phenomenon simulation, are given. The virtual experiment platform based on OSG, with friendly man-nlachine interface, plenty vivid phenomenon display, good flexibility and operability, provides a novel way for experimental teaching of electrical and electronic.
