Quat::InverseAndNormalize
Syntax
float Quat::InverseAndNormalize(); [5 lines of code]Inverses this quaternion in-place.
Call this function when the quaternion is not known beforehand to be normalized. This function computes the inverse proper, and normalizes the result.
Note
Because of the normalization, it does not necessarily hold that q * q.InverseAndNormalize() == id.
Return Value
Returns the old length of this quaternion (not the old length of the inverse quaternion).
