基于OpenGL的三维真实感仿真软件的开发

Exploitation of Three-Dimensional Realistic Simulation Software Based on OpenGL

针对目前三维绘图软件的动态仿真性能不十分突出,介绍了在Windows平台下,基于OpenGL与VC++6.0相结合的三维仿真软件的开发过程,利用Pro/E进行三维建模,然后保存为STL文件格式,在仿真软件中读取STL文件,介绍了STL文件的读取及其线面特征的重建,然后基于各零部件相互独立的思想提出了一种比大型三维软件实时性更好、更流畅的运动仿真方法,最后给出了一个动态装配的仿真实例,在仿真软件中减速器的动态装配过程。

According to present dynamic simulation performance of 3D Graphics software which is not very prominent, the development of a 3 D simulation software based on OpenGL and VC ＋ ＋ 6.0 in the platform of Windows is introduced. The three dimensional modeling is first established using Pro/E, then the STL document format is preserved, reread and line-face features rebuilt in the simulation software, and the STL document＇ s read process is introduced in detail. Based on the idea of independence, a dynamic simulation method which is more real-time and fluent than the popular 3 D design software is improved. At last a dynamic assembly simulation example is provided-reducer＇ s dynamic assembly process introduced in the simulation software.
