Abstract

In the graphic developing environment based on OpenGL, it is difficult to create complicated 3D models by encoding; meanwhile, professional 3D modeling softwares can´t meet the requirement of interactivity of a VR system. Based on the comparison between three 3D modeling methods in OpenGL, a new method is put forward, that is, to create complicated models by using 3DSMax, and have the model files exported to 3DS-format and fetched in OpenGL in which real-time rendering effects is attainable. After analysing 3DS file data structure, an arithmetic is put forward of how to read 3DS files in OpenGL, so that, both advantages of 3D modeling by 3DSMax software and real-time rendering in OpenGL are combined together. This method has been used in a virtual reality system of a certain type of launch vehicle successfully, and its correctness and serviceability have been validated practically
