Absolutely amazing video! it was very informative and helped me understand parts of quaternions that i learned in class. This video easily deserves thousands of views
wasn't your cube originally with one corner at the origin and it's opposite at 1,1,1? But later your cube seems to be centered on the origin. Is that what you intended? It's pretty hard to track the transformation of that cube, too many visual features in a small area. Actually a non-symmetric shape like your initial boat would probably be easier to track.
As an oversimplified answer: to rotate a *quaternion* with another quaternion, you just multiply them, while for rotating a *vector* with a quaternion, you sandwich the vector with the quaternion: q p q^-1.
That's fair. In the future, I'll include a part in the introduction that addresses the kinds of math that you should be familiar with or that would be helpful to know.
Good video I enjoyed it!

Iam sure one day this channel blow up ❤. Thanks for the video.

Wow who knew I would love quaternions so much!
3:27 you say r dot q performs the rotation; but then you say that to perform the rotation we must perform this operation: q p q-inverse.

I think you have to know a lot first for all this to mean anything at all. Otherwise its like a foreign language.
