The Quaternion Identity is very powerful & really quite simple - in 3D space it represents zero rotation, a place where an object is ‘perfectly aligned’ with the world around it. But it sounds far more complicated on first exposure - and when I taught VR coding, it always silenced the room & intimidated students, both newbies & experienced developers alike. In many ways, it reflects alot of technology today - seemingly complex at first glance, but able to be explained in simpler, more accessible terms. This is what I am aiming for on my blog - meaningful simplicity in understanding technology concepts. In so doing, I hope that I can better understand some of these concepts … & if the n=2 people that read my blog benefit as well, then that is a definite upside!
