Can someone recommend a good cross-platform rendering solution (for self-learning purposes)? Something that will run well across Windows, macOS, and Linux.

I was looking at building a DirectX / Metal / Vulkan project, but ran into trouble when I realized you need to use objective-C to interact with Metal, and I don't want to use objective-C for the whole project, just regular C lol

There were also things like bgfx and SDL / Raylib that kinda abstract away a lot of it for you, but I'm worried that I'll miss out on learning important things if the solution abstracts too much.
