利用OpenGL实现复杂机构的运动仿真

Using OpenGL to Realize Moving Simulation of Complex Machine

该文介绍如何利用OpenGL实现复杂机构的运动仿真的技术。为解决在OpenGL环境中建立复杂三维物体模型的困难 ,开发了OpenGL与AutoCAD的图形应用程序。首先利用AutoCAD2 0 0 0 ,创建复杂形体的实体模型 ,将之保存为 .3ds形式的文件 ,接口程序调用 .3ds文件中的模型顶点数据和材质信息 ;然后调用OpenGL函数完成建模工作 。

The technology of complex m achine's moving simulation with OpenGL is introduced. In order to overcome the difficulty of establishing 3D model in OpenGL, a graphic developing program is d eveloped with OpenGL and AutoCAD. First, an entity model with complicated shape is established by using AutoCAD2000 and saved as *.3ds file. The interface p rogram call the point data of the model and the material of the model informatio n in the *.3ds file. The OpenGL function is then called to finish the mode l establishing work and to realize moving simulation of complex machine.
