基于OpenGL的虚拟仿真实验设计

Design of Virtual Simulation Instrument Based on OpenGL

虚拟仿真实验是虚拟现实技术和信息技术的有机融合,是一种创新的教学方式。针对大学物理实验操作复杂、教学过程讲解困难的问题,在Visual C++环境下开发了OpenGL应用程序。利用OpenGL编程设计了虚拟分光计、迈克尔逊干涉仪、光的单缝衍射和光的偏振等三维虚拟仿真实验。这些项目具有以下特点:①采用三维建模,程序为单一场景;②可以进行交互操作,操作简便;③实验现象根据公式实时计算,可进行虚拟测量。实践表明,这些模型能有效地帮助学生理解相关实验,丰富教学手段,提高教学质量。基于OpenGL的虚拟仿真实验设计为物理实验教学信息化、多样化提供了一条切实可行的道路。

Virtual simulation experiment is an organic integration of virtual reality technology and information technology,an innovative teaching method,and an important part of future experimental teaching. In view of the complex operation of university physics experiment and the difficult explanation of teaching process,an OpenGL application program is developed under the Visual C++. Three-dimensional virtual simulation experiments of virtual spectrometer,Michelson interferometer,single slit diffraction and polarization of light are designed by OpenGL programming. These projects have the following characteristics:① by using three-dimensional modeling,the program is a single scene;② interactive operation can be carried out,and easy to operate;③ experimental phenomena can be calculated in real time according to the formula,and virtual measurement can be carried out. Practice shows that these models can effectively help students understand relevant experiments,enrich teaching means and improve teaching quality. The virtual simulation experiment design based on OpenGL provides a feasible way for the diversification of physics experiment teaching.
