I know enough about mathematics to kinda sorta know what a quaternion is and what complex numbers are, etc. I don’t know enough about math to know why one would use them in these sorts of situations instead of tuples/matrices.

What a great resource! I’ve been bumping against the raw edges of my utter lack of knowledge in this area so it’s always incredibly helpful when someone in the know with a talent for teaching stops and takes the time to ELI5 :)

Cool post, one could also mention how the wedge product clarifies rotation better than the typical cross product approach, and how the unit quaternions are the same as the basis for ℝ³ ∧ ℝ³.

A good source for how to code with quaternions. A while back I was looking for a source to help me actually understand quaternions on an intuitive level. It took some time but I found this

Particularly of interest because it is such cutting edge video tech. I really wish more educational videos used this kind of interaction.

If I had to sum it up (and other folks chime in if I’m wrong):

Yep! I think Eric Lengyel has a bunch of great information about that and other geometric algebra stuff.
