In LSL, quaternion multiplication is written down in reverse order as in maths :
Q2 * Q1 (LSL)
is the same as
Q1 . Q2 (maths)
Perharps that would deserve a word of explanation here.

This text has two shemas at the end. If you look well at it, the 90° rotation in the first schema and
in the second schema are supposed to be opposite (once in z direction, the other time in -z direction)
but the pink arrow materializing the rotation is the same.
It's the first schema that is correct (LSL follows right-hand rule for direction of positive rotations)

- That is correct, LSL uses right-hand rule set. (Strife Onizuka)
- So what do we do to fix this page? (Cathy Pfeffer) [PS my interpretation of z-1Qz problem was wrong, rephrased. See above]
