Hi,
I think you have miscalculated the normalisation of the dual quaternion - you've already normalised both the primary and dual parts by the primary part's norm, so following the equation in https://math.stackexchange.com/questions/4445771/normalizing-a-dual-quaternion, you should only need to subtract the dual part by the dot product multipled by m_real, without needing the * lengthSqr?

Hi, I'm trying to install dq3d and get this error, attached in the screen shot.
the transformations in already installed.
Best Regards
