Microsoft threatens OpenGL

As I predicted back in January when Microsoft bought up SGI’s patent library, they’re using the patents to threaten OpenGL.

For those who don’t know the technical details: Most of the porting difficulties with games software are because of use of Microsoft’s DirectX libraries for graphics and networking. If DirectX has been used, often the game engine needs to be totally rewritten. If Microsoft make OpenGL prohibitively expensive to use by collecting hefty patent royalties, they ensure that everyone developing games uses DirectX, and hence make sure that as few games as possible are ported from Windows and Xbox to other platforms.
