[vtkusers] vtk axes change x y and z

[ajohnston]

Hi, I am trying to hide an axis when it is perpendicular to the view plane,
i.e., very short on the screen.
It seems that xaxis, yaxis and zaxis change as the camera rotates around the
scene.  We've been trying to use the GetOrientation of the camera to know
when to hide the x y or z axis, but then the axis names keep changing, so we
get random results.

Also, I would like to use the angles calculated to rotate the alignment of
the axes labels.  When we do that, the labels get tiny, probably because
they are getting scaled to the horizontal text height.  Previous versions
posts seem to have this solution, but vtkAxesActor does not give me that
method.

axes->GetYAxisCaptionActor2D ()->GetTextActor()->SetTextScaleModeToNone(); 

Cheers, Adam
