Hi Martin,

You have a great page there that's really cleared up in mind quaternions and rotations and how to convert between them all.

I just noticed a mistake in your example of rotating the point (1,0,0) to (0,1,0) with a quaternion on the page

https://www.euclideanspace.com/maths/algebra/realNormedAlgebra/quaternions/index.htm

There were a few small mistakes in the maths e.g. ki = -j and then in your explanation, you said a negative angle gives anticlockwise rotation, but anticlockwise should be a positive rotation angle.

Cheers,

Richard
