OpenGL是个与硬件无关的软件接口，可以在不同的平台如Windows 95、Windows NT、Unix、Linux、MacOS、OS/2之间进行移植。因此，支持OpenGL的软件具有很好的移植性，可以获得非常广泛的应用。由于OpenGL是图形的底层图形库，没有提供几何实体图元，不能直接用以描述场景。但是，通过一些转换程序，可以很方便地将AutoCAD、3DS/3DSMAX等3D图形设计软件制作的DXF和3DS模型文件转换成OpenGL的顶点数组。-OpenGL is a hardware independent software interface, can be on a different platform such as Windows 95, Windows NT, Unix, Linux, MacOS, OS /2 transplantations performed between. Therefore, support OpenGL software with good portability, can get the very extensive application. Because OpenGL is the underlying graphics graphics library, provides no geometric primitives, cannot be directly used to describe a scene. However, through the conversion process, can easily be AutoCAD,3DS/3DSMAX and3D graphic design software DXF and 3DS model file into a OpenGL vertex array.
