If you’re looking for some great content that is completely unrelated, I’d recommend either Keenan Crane’s Discrete Differential Geometry course (
https://www.cs.cmu.edu/~kmcrane/Projects/DDG/ and
https://brickisland.net/DDGSpring2021/) or Peter Shirley’s Ray Tracing in a Weekend Series (
https://raytracing.github.io/). The former is a little more math heavy/in-depth, whereas the latter is a little more abbreviated. Both are super fun and expose you to some really exciting and powerful ideas from Computer Graphics.
