  1. OpenGL Get Context

    Quote:Original post by BionicBytes It would seem that you do not have a valid glViewPort() values. ... which may imply an invalid context. Can you be sure that when you call this method you really do have a valid gl context? 1st Thanks for the replay. So how to check that its valid or not?

  3. OpenGL Get Context

    Quote:Original post by LordOrion Hi, I'm not an expert of C# and how it is interfaced with OpenGL, so I cannot help you with the context... but seeing your code I've noticed that you are trying to read pixels from the Back Buffer: GL.glReadBuffer(GL.GL_BACK); Try read the front Buffer instead. Back buffer is often cleared immediately after the swap or immediately before begin a new frame so you cannot rely on its content. I hope this can help Thanks for your help but GL_FRONT Same Black Screen. But im buidling it in C# but C++ ways help allsow.
