Dear vtker's,<br>
No answer yet, so does it means that I'm now the only one having
this problem ?<br>
Herebelow is a small example program that illustrate this
incompatibility between vtkInteractorStyleTerrain and
vtkAxesActor/vtkOrientationMarkerWidget.<br>
Any idea/comment ?<br>

<div>Answering to myself, just to mention that similar problem has
already been reported in the mailing list, but I could not find
any answer.</div>
<div> </div>
<div>So does this means the only solution is not to use
vtkInteractorStyleTerrain with vtkOrientationMarkerWidget??</div>
<div> </div>
<div>Thanks for any tip/advice</div>

<p>Hi all,</p>
<p>when the vtkInteractorStyleTerrain is used with
vtkAxesActor/vtkOrientationMarkerWidget:<br>
- the following error message is obtained "Resetting view-up
since view plane normal is parallel"<br>
- the orientation of the vtkAxesActor gets wrong when
viewing along the z-axis.</p>
<p>Is there any way to correct this behaviour (apart from not
displaying the warning message)?</p>
<p>Thanks</p>
