Research of 3D Modeling of Virtual Reality for LAMOST Based on OpenGL

In order to improve the observation efficiency of the Large Sky Area Multi-Object Fiber Spectroscopic Survey Telescope (LAMOST) and facilitate the operation, Virtual Reality (VR) technology is used to realize the graphic control interface of LAMOST. It is difficult to create the complicated 3D models for the LAMOST VR system by using traditional modeling methods. A new method is proposed. Firstly, we apply 3DS Max software to create the 3D models of LAMOST, and then the models are exported to an ASCII Scene Export (ASE) file which remains the shape, material, and texture of the 3D models in 3DS Max. ASE format is an ASCII structure file format which is native to 3DS Max. Finally, the ASE file is analyzed and each object is rendered by OpenGL in real time. Based on the method, a 3D model of the LAMOST spherical primary mirror system (SPMS) is completed. Test result suggests that this method can be used to develop the VR system for LAMOST.
