What a magnificent presentation! As Freya puts it herself, it is not so much that she is introducing something new, but showing how and why complex numbers and Hamiltonian Quarternions are (or can be) a useful part of VGA (what exactly does that VGA stand for again? )
TBH the whole “What happens if we treat complex numbers as vectors” and then slow walking us into “rediscovering” all the other products of vectors
Her videos on Bézier splines are my comfort movies.
Currently playing with Processing
