Reddit reviews OpenGL Programming Guide: The Official Guide to Learning OpenGL, Version 4.5 with SPIR-V (9th Edition)

Well, you can't really go wrong with OpenGL Programming Guide: The official guide to learning OpenGL also widely known as "the red book". It has been a staple for learning OpenGL for decades, and the recent version is updated to OpenGL 4.5 which is one minor-version away from the latest version.

The only downside is that the latest edition of the book has taken a nosedive in layout- and typographic quality; my earlier book from around 2003 had color images of great quality and was laid out well. Read the reviews before purchasing. Also, the red book does not work well as a standalone tutorial in my opinion; use it as a supplement in addition to other sources. Specifically it lacks a more 'high level' perspective. It assumes much of the reader's academic or professional background.

I don't expect any new great books on OpenGL being published anytime soon. The API is considered 'final' after version 4.6 and Vulkan is generally taking over OpenGL's responsibilities regardless of whether Vulkan truly is feasible to use in the same application domains as OpenGL. That said, any book from 2010 and upwards that covers OpenGL 3.0 or later is still reasonably close to the latest version in my opinion. Once you get the basics down, you can consult each later OpenGL specification to figure out the incremental changes. The changes in each OpenGL version is mentioned in its own appendix at the end of the specification. For some years now you can even download a version of the OpenGL specification which has all the changes marked in highlighted color and/or strikethrough, which also helps. When learning OpenGL, https://www.opengl.org/registry is an invaluable resource.

The best answer to your question is to read the "red book" (probably free online somewhere but i prefer the paper myself).

If you really like graphics I recommend reading it cover to cover. That will help you a lot, it did for me.

then you can go with this online tutorial

or get a book 1

2

go with online tutorial then as you get comfortable go with the contents of book.
