> Let me stress here that while this collector is simple, it isn’t a toy.

> There are a ton of optimizations you can build on top of this—in GCs and programming languages, optimization is 90% of the effort—but the core code here is a legitimate real GC.

> It’s very similar to the collectors that were in Ruby and Lua until recently.

> You can ship production code that uses something exactly like this.

> Now go build something awesome!

Bob Nystrom also has a blog, and his articles are really well written (see his post on Pratt parsers / garbage collectors). I'd also recommend going through the source code for Wren, it shares a lot of code with Lox. Despite the deceptive simplicity of the implementation, it (like Lox) is incredibly fast - it's a great way to learn how to build production grade compilers in general.

Bob Nystrom (of Game Programming Patterns, Crafting Interpreters, and dartfmt fame) also wrote a tutorial[1], of a precise as opposed to a conservative garbage collector.

Regarding register scanning, Andreas Kling has made (or at least quoted) an amusing observation[2] that your C runtime already has a primitive to dump all callee-save registers onto the stack: setjmp(). So all you have to do to scan registers is to put a jmp_buf onto the stack, setjmp() to it, then scan the stack normally starting from its address.

Might not be that hard: https://journal.stuffwithstuff.com/2013/12/08/babys-first-garbage-collector/

To better understand garbage collection, nothing better than implementation. This article is such a joy to read:

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?
