well, I am not new to OpenGL, I already did some smaller projects, so I understand the framework. But now I am lost.
To this time all my programs were on NeHe’s framework, now I decided to build my own, that better suits my needs. BUT… It does not work. After the initialization, almost no gl calls seem to perform their tasks. Some do. For example glGetString returns correct driver name, but when I want to clear the screen or draw something, it does not work. Just the window background I specify during window creation stays all the time there, unchanged. I am lost.
I even tried to copy the key parts of NeHe’s programs in to my own and I know the initialization is in the right order. PLEEASE HELP !!
I tried error checking, but glGetError returns GL_NO_ERROR.
And about those matrices, all I do is just set up the perspective (or orthogonal, I tried both) projection. But even the glClear(GL_COLOR_BUFFER_BIT) does not work. NO OUTPUT at all. I am confused.
