framebuffer object

  1. Default framebuffer object

    hi all,

    i want to map a dynamically drawn 2d window to a 3d cube...or i want
    to map dynamically drawn texture to 3d cube...i got some code for
    frame buffer object which does this but have some problem...


    char *ext = (char*)glGetString( GL_EXTENSIONS );
    if( strstr( ext, "EXT_framebuffer_object" ) == NULL ) //this returns
    NULL
    {
    }


    "EXT_framebuffer_object" is not found...i imported "glext.h" from
    internet but still its not working and my "glext.h" will also not
    work...is this opengl version problem?

    You already asked this on comp.graphics.api.opengl, and the correct
    answer was provided: The OpenGL driver for the graphics card on
    which you are running does not support framebuffer objects. On such
    cards you should fall back to using pbuffers.

    Regarding extension handling, consider downloading a package that
    already takes care of the details. For example, GLEW is a decent
    package that can be downloaded from http://glew.sourceforge.net .
