Hello,

As far as I know, VTK doesn’t have anything like that. A quick answer: use C++'s `<cmath>`'s `atan2()`. A gimbal-lock-proof answer: Eigen library. See [Equivalent rotations of a set of rotations. - #3 by Paulo\_Carvalho](https://discourse.vtk.org/t/equivalent-rotations-of-a-set-of-rotations/8355/3) .

take care,

PC
