Two Good Books for an Intro to Quaternions

Here’s a good intro tutorial on Quaternions for Unity3D from Unity Gems. It comes w/ a sample .unitypackage.

For a more in depth understanding, the following two books might help.

I liked the Quaternions section in the 1st edition because it gave you more context by going over Complex Numbers and performing addition, subtraction, multiplication on them first:

3D Math Primer for Graphics and Game Development

I’ve looked at the 1st edition of this book for an overview of Quaternions and it was fairly straight forward but no overview of Complex Numbers:

Essential Mathematics for Games and Interactive Applications: A Programmer’s Guide
