Study Of Geometric Modeling Technology For The Electromagnetic Compatibility Analysis To Communication Vehicle Based On OpenGL

The analytical software for the electromagnetic compatibility is the tool with which we can use computer to help us to complete the design of electromagnetic compatibility. There is no limit on the objects analyzed, and the procedure is very easy .Also the software reduces the time and the cost which incarnates the superiority of the analytical software.This paper focused on the model visualization technology and the mesh partition technology. In geometric modeling aspects, I use business software to build the entities models. And using the ACIS file as an intermediary file,our system can the geometric models into the surface models for using of electromagnetic compatibility analysis software.The system can pick up the worthy information from ACIS file,and can transform the complexity surfaces into the easily surfaces. This method is reliable and easily. In the method of pre-partition of complex surface, the system uses the top-down form to partition the complex surface. Practice has proved that the algorithm is simple and reliable. In addition, the paper made a theoretical research for the method of model editing function based on OpenGL.
