Starting OpenGL with Qt

[d_stranz]

Does Qt cover all what OpenGl has?

The QOpenGL... classes cover a large part of OpenGL, but really they are just a very thin wrapper around the core OpenGL functions. See QAbstractOpenGLFunctions. You still need to learn OpenGL itself to be able to use them. If you read a book on OpenGL and learn it that way, understanding and using the Qt wrapper will be easy because there is nearly a 1 - 1 match between the names of methods in OpenGL and the Qt wrapper.

One other book I forgot to mention is the "OpenGL Super Bible", a good companion to the "red book". Be sure to get the latest versions of any book you buy. OpenGL has changed a lot in the last 10 years and you don't want to be teaching yourself from an obsolete book.

Thank you very much for your guidance.

I also found other books useful for learning.

As the decision point, which of those four books would you recommend me if I only have time for one of them now, please?

The "learnopengl" book looks like a good place to start before you buy anything.

I think you pretty much have to buy the red book at some point (OpenGL Programming Guide). I have a very old copy of the OpenGL Superbible (2007), but I ordered the latest edition this week. When I receive it I will let you know if it is worth having.

Otherwise, there are a lot of excellent online resources, as you are discovering.

Thanks so much.
I could find the red book 9th edition and I'm reading it now. It seems great it starts from OpenGL 4.5 and it's my choice for learning OpenGL.
