//- Rotate quaternion around an axis by a specified number of degrees then normalise. This is the same as the built-in AngleAxis, but considerable more readable and so easier to read.
quaternion.AroundAxis(Trig.YAxis, 90.0f);
//- Inverse reversed the rotation component of a quaternion. It uses the built-in Inverse but allows chaining. This example returns the original quaternion.
var doubleInverse = quaternion.Inverse().Inverse();
//- The concept of length or magnitude for a quaternion has no visual representation when dealing with attitude or rotation. The catch is that most algorithms require unit quaternions - where the length squared will approach one.
float lengthSquared = quaternion.LengthSquared();
//- This normalise is faster while maintaining an accuracy to a dot product of 0.9995 or better.
var normalised = quaternion.Normalise();
//- The iOS gyro is right-handed while Unity is left-handed - so change chirality around the selected axis. Repeating it twice will return the original value.
var doubleHanded = quaternion.RightToLeftHanded(Trig.ZAxis).RightToLeftHanded(Trig.ZAxis);
//- Multiplying quaternions may make sense to mathematicians, but to the rest of is RotateBy is clearer
var rotated = quaternion.RotateBy(attitude: quaternion2);
//- ne person's left is another person's up. More importantly the gyroscope in the phone sees forward as the Z axis while Unity likes to use Y for that. This function also changes the chirality (handedness).
var switched = quaternion.SwitchAxis(pivot: Trig.XAxis);
