Quaternions Explained by Dan

An overview of what quaternians are, how to do a basic rotation in 3d space, and how to use software to do it easier. Made because I thought I worked harder than I should've needed to to rotate things in 3D space myself! If you're trying to do quaternion arithmetic yourself, my favorite guide is here:    • Quaternions Part 3   It involves lattice multiplication, so you'd better be prepared! Khanacademy has a great primer here: https://www.khanacademy.org/math/arit... And for a more detailed introduction, this much more personable teacher has appeared on the youtube scene since I made this video, and I've heard great things about it:    • The rotation problem and Hamilton's discov...   Good luck!
