The answer you figured out on your own is the basic principle of needing to translate your coordinate system to the appropriate origin before rotation. Graphics tutorials often cover this topic as well, so those may be a good place to look for a good linear algebra introduction. Sorry that I don't have a good link on hand to give you, but Google should find you some useful material. | |
