    Index buffer objects (IBOs) can only have one set of indices for rendering. Since you're trying to render an .obj file, you typically need three sets of indices: position, normals, and texture...

    Your question is not about OpenGL but general programming. What do you normally do in any C++ program when you have the compiler tell you that "somefile.h" is missing? Learn C++ first and all the...

    My reaction was in response to your apology for being "new to the whole C/C++ library system" which is a beginner's remark. Glext.h does not load GL functions, but defines the GL symbols beyond GL...

    This is a math question, not an OpenGL question, so in the future don't expect people to answer you. The normal matrix is the matrix which preserves vertex normals under an affine transform. If you...

    You're trying to get a core profile but you're manually including glu.h and gl.h. I always seem to have trouble if I include those headers. Try getting rid of those and also use glewExperimental if...

    Re: Can't compile shader anymore

    There isn't enough information here to determine why the compile fails. You should paste the code that's causing the problem. For example, are you reading the shader from a file and returning it as a...
