Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Blaze: A High Performance C++ Math library
Is Eigen still alive? There's been no release in 3 years, and no news about it: https://gitlab.com/libeigen/eigen/-/issues/2699
- Gentoo -Os vs -O3 application startup time?

The Case of the Missing SIMD Code
I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?
I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

FetchContent and PROJECT_IS_TOP_LEVEL
I am trying to include Eigen in my project via FetchContent. They define/assume-defined PROJECT_IS_TOP_LEVEL on line 19 and, among other locations, on line 607 in their top level list file.

Common practices when doing image processing on the GPU
Eigen is a header-only library, thus simply cloning it from the official repository into the FOGGDD folder should be enough.
- Use TFlite in a Cmake Project

I've decided to learn Godot and it feels like I have "lost"
math library because you should never implement a math library yourself, and you probably want somethign more focused on performance than STL. GLM may work if you just need basic vector support. Eigen may help for a more physics heavy game. But I'd probably find something in-between those two

Is it possible and realistic to learn independent of an API?
Sort of, I'd recommend a modern higher level API. I'm not sure what the current recommended ones are (probably bgfx), but assuming the wrapper is "low level enough", then the concepts you learn are still going to apply.

Best graphics libraries for game development that are compatible with Apple Metal API?
bgfx. I have not used it, but I have heard good things about it.

LWJGL = SFML vs Allegro vs SDL vs Ogre vs ???
There's kind of a lack of this for C++ in 3D, I think it's often due to the necessity of a secondary scripting language in game engines with C++, which isn't necessarily needed in Java or C#. SFML is like that (but also 2D), Godot is similar (but more geared towards 2D). Ogre3D is an actual engine like I mentioned earlier, not sure how easy it is to use. Cocos2d is higher level, but is also 2D only. I'm not fond of SDL, it feels like a windowing library with slow old school immediate mode stuff attached, so it ends up not being good at the rest of the tacked on things. SDL is popular as a windowing library, and it's why you see it used everywhere (but the most notable uses of it aren't using their drawing capabilities), I often see bgfx thrown around, and for you it might be a good choice, though I have no experience with it.

Is it a crazy idea to create a 3D operating system?
Another route could be using an abstraction over Vulkan (faster, more efficient, more difficult): bgfx, dawn, magma, or wgpu (Rust).

The update we all want but will never get
now, java is actually quite a performant language and even if its not most of the performance bugs in mc are due to it being single threaded, inefficient chunk generation and optimizing, and it built ontop of opengl WHICH isn't much of a performance hit but its still ehh idk it doesn't matter that much (NOW SWITCHING THE GAME TO AN ENTIRELY DIFFERENT GRAPHICS API WOULD SUCK ASS TO DO (and vulkan is quite verbose :))) (AND also bgfx would probably be better due to it being an abstraction layer ontop of all the graphics apis so minecraft could target many depending on your platform (and also bedrock used to (or still does i dont know) use bgfx before they switched to just two (IF IM READING MC WIKI RIGHT BECAUSE IM NOT ENTIRELY SURE IF THEY USE BGFX STILL ?? SO THEY COULD STILL BE TARGETING MULTIPLE YET THEY JUST WROTE THEIR NEW SHIT BAD IDK))
