Design and Implementation of 3D Simulation System for Air Volume Balance Based on OpenGL

With the development of intelligent manufacturing, simulation technology has become one of the important research of industrial simulation systems. This paper proposes a method for realizing a industrial simulation system based on the BIM technology and the functional mockup unit (FMU), which can be applied to many industrial fields. We analyze various methods of loading three-dimensional models by OpenGL, and provide the specific implementation process and technical points. What' more, we realize the interactive operation of three-dimensional model through programming. Finally, we propose a method for information exchange between FMU and simulation system. As a result, data simulation and virtual simulation of 3D scenes are all realized.
