几种三维模型文件在OpenGL中的输入与处理
IMPORT AND MANAGEMENT FOR SEVERAL 3D MODEL FILES IN OPENGL
【摘要】 介绍了一些当今比较流行的三维文件的文件格式,如3DS文件、OBJ文件、WRL文件等,并论述了如何将这些文件在OpenGL(Open Graphic Library)中进行输入和处理。重点介绍了OBJ文件的文件格式及怎样利用程序代码来构建模型数据结构、绘制对象模型,然后运用Open-GL的强大功能实现三维显示和交互操作,并应用于地形建模、城市规划,以及虚拟现实等领域。
【Abstract】 The file formats of several prevalent 3D files such as 3DS,OBJ and WRL files are introduced and the ways how to transfer 3D model files to OpenGL are discussed.The paper lays a strong emphasis on the file formats of OBJ file and how to use code to form the modeling data structure and how to paint the object models.Then the powerful function of OpenGL can be used to 3D display and interactive operation.These methods can be applied into many fields such as the terrain modeling,the city planning and the virtual reality.
