    GL extensions and nVidia

    Hi,

    I don't understand why my card (GeForce2 Pro) does not support WGL_EXT_extension_string or WGL_ARB_extension_string. In nVidia ext. specifications I found that it is supported with NV1x and later chipsets. Also I found that NV_vertex_buffer_object is supported with detonators R40. I haven't got VBO. I've got detonators 43.45, so what's going on?

    Thanks in advance

    Try to f**k this ext string & call getprocaddr for everything you need, if pointers are nulls, sorry, if not, they just forgot to type exts in string

    Thanks! It worked. I got upset with it, what the heck is glGetString(GL_EXTENSIONS) for?

    it's kinda tells what extensions are available with your implementation but offen misses occurr like this one.Everything is documented thought so not to worry!

    i've got geforece 2 ti and updated the driver to the 4.4.0.3ӣWell the opengl extension does include Vertex_object_buffer .
    Another thing you might do is to download the lesson24 application from NeHe. Lesson 24 can check out how many extension your Graphic card support.

    From the OpenGL specs:

    "Applications should call wglGetProcAddress to see whether or not wglGetExtensionsStringARB is supported."

    The nVidia drivers are doing the right thing.

    OK, Looks like that I will have to get detonators 44.03. But with my modem connection it'll be too expensive (18.8 MB file).

    Thanks
