If textbooks are more your vibe, OP, I’d also look into Real Time Rendering. Solid foundations with later chapters delving into modern techniques. They keep their editions fairly fresh too!

I would also recommend that one. Those two were the foundation for my graphics knowledge when I was learning.

I actually have that one on my shelf already, just finding the time to delve into it!
