bgfx VS Torque3D

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.

https://github.com/bkaradzic/bgfx for just that FOSS intermediate rendering library (includes Minecraft)

BGFX: Pretty mature and easy to use with many backends.

bgfx. I have not used it, but I have heard good things about it.

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.

Another route could be using an abstraction over Vulkan (faster, more efficient, more difficult): bgfx, dawn, magma, or wgpu (Rust).

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))

On a similar note, released games with open sourced code: https://osgameclones.com/?tag=official

https://torque3d.org was used on Airship Dragoon, Marble Blast Gold, Penny Arcade Adventures, Legions: Overdrive and descends from the original Tribes engine.

Hellbreaker, Bit Champs with https://u3d.io

And plenty of successful games with Ogre, including Torchlight: https://www.ogre3d.org/showcase

Torque 2D/3D: Didn't do too much digging around on this one, but both versions are MIT licensed like Godot, but it seems like the project is a little more mature, with built-in multiplayer support. Could be worth looking into as an alternative to Godot if you really want something with MIT licensing.

But from now on, I think I will abandon that, and continue with Torque3D engine : https://torque3d.org/

Torque3D- This one seems great for beginners, as it's free and open-source. The downside is, I'm not sure if it has enough features for complex projects or how secure it is.

Torque3D (the engine used to make Tribes 2, now open-source)

No lie, that overall looks a lot like a game done for a senior design project 15+ years ago using Garage Games' (now https://torque3d.org/) RTS kit.
