A Study and Realization of 3D Visualization of Railway Sleeper Model Based on OpenGL

Sleeper is an important part of railway track.The quality of sleeper directly affects the operation safety of train.Based on J-2 concrete sleeper,the concrete sleeper model is researched through the analysis of sleeper section and the calculation of coordinates.The implementation process of 3D visualization of sleeper is also described by using OpenGL in Visual C++ programming environment after reading the model data.
