RayTracer VS LearnOpenGL

And here there is a project of mine base on them (and not only): aromanro/RayTracer: A ray tracing program (github.com)

I've got a basic obj parser in my ray tracing project: https://github.com/aromanro/RayTracer

And this one: https://github.com/aromanro/RayTracer is with ray tracing, not using opengl, but it illustrates spheres that are 'really' spheres, that is, not made out of polygons. In principle such thing could be done with opengl as well (or some variation of it).

I started out with 'Ray Tracing in One Weekend' (actually it was in very few hours in a Saturday), then went further, first with the other two volumes then with some papers and other things on the net and in the end I've got this: https://github.com/aromanro/RayTracer

I started with number 2 (continuing with the other two in the series), then went further and ended up with this: https://github.com/aromanro/RayTracer

Also recommended: LearnOpenGL [1] and Vulkan Guide [2]

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?

- Game development - Unity3D project based learning in C#: https://learn.unity.com/ - Graphics - There was another user on r/GraphicsProgramming the other day (who teaches Computer Graphics at his university) that linked their lecture series for the entry year of their course here: https://tamats.com/learn/realtime-graphics/ - Project based learning: https://github.com/ssloy/tinyrenderer/wiki - Rendering API tutorials: https://vulkan-tutorial.com/, https://learnopengl.com/

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Possibly a smidge outdated.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.

and then https://learnopengl.com/

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?
