With the achievement of China's lunar exploration project, the last task of achieving lunar soil sampling unmanned on the lunar surface and return safely will be executed. To be able to simulate the status of the probe, Autodesk 3dsmax is used to create the probe 3D model and transfer the 3DS format; C++ and OSG library are combined to implement the 3D reconstruction visualization. The experimental results show that OSG library can meet the needs of visual display, and provide some references for the visualization of the lunar exploration project.
