I followed a book in the 90's to create a flight simulator from scratch. Besides learning Bresenham's line algorithm, I learned a lot of linear algebra.
Probably this book: https://archive.org/details/build-your-own-flight-sim-in-c-d...
I always recommend “Ray Tracing in One Weekend” [1] series of books for some light coverage of linear algebra/geometry/graphics.
I was 13 at the time, so I struggled with the math (this was pre-internet so I couldn’t just search stuff). I’d never seen matrices and wasn’t able to figure them out from that book. I distinctly remember hitting a wall in the chapter on lighting because it mentioned taking the dot product of two vectors, but I didn’t understand why that would give you the cosine of the angle between them because I’d never heard of the dot product before.
Edit: right at the bottom of page 405. I reread that sentence so many times.
