基于OpenGL的惠斯通电桥的模拟实现

The Simulation Implementation of the Wheatstone bridge Based on OpenGL

基于OpenGL的惠斯通电桥是利用OpenGL的纹理贴图技术及拾取功能来编程实现的。该软件是通过鼠标模拟其操作过程,双击左键可以开关电键,移动鼠标可调节滑动变阻器的滑动触头,来使电桥达到平衡。该软件还可进行基本的数据处理。直观形象的图形效果,不但可以使学生加深对电桥工作原理的理解,还可使实验教学更生动,激发学生的学习兴趣。

The Wheatstone bridge based on OpenGL is implemented by programming utilizing OpenGL＇s texture image technique and picking up function. The software simulates the operation process by the mouse, that is double clicking the left button to switch the key, and moving the mouse to adjust the sliding contact of the sliding Rheostat, so as to make the bridge balanced. The software also can make basic data processing. The intuitive graphics effect can not only deepen students＇ understanding bridge＇s working principle, but also make the teaching of the experiment more lively, and stimulate students＇ study interest.
