Hi, Have you tried multiplying the matrix of each of these rotations to get the resulting single rotation? That is: let's say we have three rotations as follows: rotation 1 0 0 x rotation 0 1 0 y rotation 0 0 1 z you put them together by doing: Transform3D xrotation = new Transform3D(); Tran

Hello, I have a set of three rotations around the standar xyz axes. I wish to concatonate them into a single rotation - I understood this to be called Eigen axis- I guess there must be an algorithm, I believe the aeronautical/space community need to do this. I've had a look at Matrix and various
