HeadTracking Rotation does not match

[ChrisMa]

Hello everybody,

I really tried hard. But I don't get the Rotation of my Head right. The positional tracking works as I wanted it. Is swapQuat the right command for it? For example, if i roll the Headtarget the view pitches upwards. I don't understand the positions in the swapQuat. 1,2,3 means Rotation around the x,y,z achses from my tracking Device, right? My Tracking Target has the z-axis in viewing direction, y to the sky and x to the left.

The Position in the matrix coresponds to the axis of my mainview. This is Z in the direction of my view and x to the right and y in the sky, right?

head.swapPos([-1,3,-2])
head.swapQuat([-1,3,-2,4])
HeadLink=viz.link(head, viz.MainView)
HeadLink.preEuler([0,0,270])

I just dont get it what to do. Can you help?

Thanks a lot for a quick reply!
