glad VS LearnOpenGL

there's glad (https://github.com/Dav1dde/glad) which you can use as a single .c file + .h header that defines OpenGL stuff or a single header-only file. I use it on all of my OpenGL projects!

If you run into a similar issue with another extension, you need to manually add extensions when generating the GLAD loader.

GLEW/GLAD: Libraries that manage and give access to OpenGL functions and extensions. The difference is that GLAD allows for greater flexibility & customization for more recent versions of OpenGL. However, the Udemy course that I'm following uses GLEW and at least at this point, I prefer to follow along with the tools that each resource recommends.

I downloaded glad from this website : http://glad.dav1d.de/ I was also referring to this tutorial to setup my project : https://learnopengl.com/Getting-started/Creating-a-window

Not sure what you're asking, what is your end goal? If you opt for glfw look at the glfw docs: https://www.glfw.org/documentation.html and/or https://github.com/Dav1dde/glad/blob/glad2/example/c/gl_glfw.c for GLAD

Just link to GLAD if you're going to link to it! https://github.com/Dav1dde/glad

glew is a GL extension/loading library, OP didn't write glew, personally I use GLAD (https://glad.dav1d.de/) in my projects, which is pretty much the same thing but auto-generated for you based on your project requirements.

In general nobody really uses the gl headers because they are super outdated and, i believe, only use Microsoft's software renderer for OpenGL. You should use a OpenGL function loader like GLAD instead.

Just use a library like glad which loads everything at runtime under the hood (even system OpenGL runtime, no need to link anything). For a quick start, there is a website to generate headers and a single glad.c to put in your project: https://glad.dav1d.de/

I want to begin game development as a hobby, but I'm unsure where to start. I did follow through https://learnopengl.com/ a few years ago, and while it was a very interesting experience, I imagine I would need to use an existing engine to be productive.

Do you recommend any books and tutorials aimed at experienced programmers with 0 knowledge of game development/design?

If u want to make 3D game, you'll probably want to learn some 3D shader graphic stuff. OpenGL is a good start. https://learnopengl.com

LearnOpenGl.com

Possibly a smidge outdated.

Goes from blank window to rendering 3d meshes with advanced lighting techniques (HDR, SSAO and more).

Heped me understand shader pipeline, so I recommend it.

I'm reading the guest article about frustum culling on learnopengl.com and there's a video demonstrating how it works and for debug purposes they have a bunch of spheres turning red or green which I assume means they're being culled or not so my question is if I wanted to do this do I have to make a mesh for whatever bounding volume shape or is there a specific method for something like this?
