I'm new to Qt, and I'd like to learn about opengl to do a 3d plotting for my project. I tried following the tutorial online, but somehow there are errors to my code. I couldn't figure out what's wrong with it since I'm pretty new to Qt. I know that there are some examples online on opengl, but those aren't really helpful to me. Can anyone point me to a place on where to start learning about opengl in qt? It'll also help if there is an opengl example code.
