微软提供较少的标准支持，对于和他们竞争的东西—比如CORBA(COM的竞争对手)和OpenGL(DirectX的竞争对手)。
不过在C＃中实现Opengl也并非没有可能，有很多很好的第3方库可以使用，这里列举2个。
（1）CsGL
http://csgl.sourceforge.net/index.html
名气较大的opengl库，有稳定版本。sf上的项目地址http://sourceforge.net/project/showfiles.php?group_id=33241。
目前有多个3D引擎项目使用的这个库。

（2）CSopenGL
http://www.ia.hiof.no/gb/ptools/csharp/p-csharp.html
有较详细的文档和例子。sf上的项目地址http://sourceforge.net/project/showfiles.php?group_id=54966&package_id=49782。

CSopenGL的一个例子（我在VS2005上编译)
