Can someone tell me where i can download the OpenGL 1.3 or 1.4 API?? I have OpenGL 1.2 but it fails to recognise the gl2DConvolutionFilter(); function. So i need an update.
This question gets asked about twice a week. It depends on your OS. If you are running Windows, you can only statically link to (i.e., get your compiler not to complain about) version 1.1 functions. You can get the latest versions of the API from your video card vendor’s website, but you have to get the pointer to the new functions with wglGetProcAddress, just like they were extensions.
