[VEX for Algorithmic Design] E14 _ Quaternion Basics

This is a new series I've started explaining the basics of VEX for algorithmic design / procedural modeling which I'm using on daily basis.

In this 14th episode, I'm explaining the basics of quaternion, how you can use it for rotational transformation in Houdini with VEX together with some examples.

I've also started a Patreon, it would be great if I could get your support to continue creating tutorial contents.

00:00:00 Intro / What is Quaternion?
00:04:23 Declare Quaternion
00:10:41 Rotation with Quaternion
00:16:53 Exercise - Rotate Object
00:23:23 Exercise - Spiral Rotation
00:27:54 Euler to Quaternion
00:42:56 Quaternion to Euler
00:47:13 Quaternion Blend with Slerp
01:00:20 Exercise - Rotational Animation
01:19:11 Orient Vector with Dihedral
01:24:19 Exercise - Animation with Dihedral
01:39:02 Next Topic - Matrices Basics
