Research and Application on the Method of 3DS File Read, Render and Control

OpenGL is a strong there-the graph develop tools,3DS format is a common format for saving there d model Based on OpenGL, the paper researches on the method of 3DS model file read, render and control. First it analyzes the file structure of 3DS, and abstracts the data structure of face, material, object and model by chunk structure used to read in data. The file data is read in with the method of recursion, the read data renders in screen after data disposal. The interactive control of model is accomplished by three kinds of geometric transformation, translate, rotate and scale and OpenGL select mechanism. Finally, those methods are applied into the system of the borehole operation operate simulation and drilling, and achieve better results.
