I'm not a mathematician and have spent countless hours with the internal workings of quaternions trying to make sense of them enough to actually use them - finally - I can use them. I don't know how widely read this thread will be but if anyone wants to ask HOW? I have the code to use them. It is a real pig but once set up it verges on the magical. Ask and it shall be given.
Avoiding Gimbal Lock using Quaternions |
I've heard of the Advanced Flat Earth Society scientists recruiting quaternions to... Well, never mind.
The brilliant and amazingly generous Martin John Baker has created a wonderful website here:

Lord Kelvin, 1892: "Quaternions came from Hamilton after his really good work had been done; and, though beautifully ingenious, have been an unmixed evil to those who have touched them in any way, including Clerk Maxwell." |
