Hi Peterakos, The bulk of the OSG loaders assume that world coordinates have +ve Z upwards, +ve Y north and +ve X to the east.
The majority Camera Manipulators assume the world has Z up as well, then set up Camera's view matrix so the Z up aligns with vertical access of the screen, +ve Y into screen and +ve X to right. You can change the default viewing position in the camera manipulators if you wish by use the setHomePosition(..) method, or avoid the use of Camera manipulators and just set the viewer's Camera's view matrix directly using any of the Camera::setUpView*() method.
