How to use newer versions on XP?

OpenGL
1

I want to use 1.2 or 1.3 features (like GL_CLAMP_TO_EDGE), and they aren’t in my uSoft 1.1 gl.h file. GLInfo says my 3dlabs card is using version 1.3. Can I use these features? If so, tips greatly appreciated.

Thanks,

Paul

Windows only supports OpenGL 1.1 natively, but allows you to retrieve function pointers to newer GL extensions via wglGetProcAddress. To use features in versions of OpenGL higher than 1.1, you’ll have to call wglGetProcAddress for every function. That’s a little painful >_< Fortunately, several people have started putting out GL Extension Loading Libraries that take care of all of this for you :slight_smile:

I’ve quickly become a fan of GLee and highly recommend it. GLee Download Page

Hope that helps :slight_smile:
