I've gotten no replies to this question. Does that mean that no one
else has had this problem?<br>
<br>
Can someone please confirm that they're using panning with
vtkInteractorStyleTrackballCamera without any problems in 5.10?<br>
<br>
Thanks.<br>

I tried panning in ParaView and the clipping works properly. Is it
using the vtkInteractorStyleTrackballCamera or something else?<br>
<br>
The problem is that it looks like the rotation center is wrong
after panning, causing the model to be rotated out of the clipping
range. It looks like the rotation center is the center of the
window instead of the center of the model. Also, I have multiple
actors in the scene. Could that be a problem?<br>
<br>
I'm not doing anything (that I can tell) to affect this. Could it
be a bug in VTK 5.10? If so, does anyone know of a workaround?<br>
<br>
Thanks!<br>

I notice that when using the vtkInteractorStyleTrackballCamera
panning, I'll subsequently see a clipping problem if I rotate
the actors afterwards.<br>
Calling ResetCameraClippingRange() on the renderer has no
effect. I'm using VTK 5.10.<br>
<br>
Is there a workaround for this? It seems like a pretty serious
problem. I searched the archives without much success for a fix
for this.<br>
<br>
Note: Back in October 2008 (5 years already!), when I was
prototyping with VTK, I posted a fix to vtkusers and <a
moz-do-not-send="true" class="moz-txt-link-abbreviated"
href="http://www.vtk.org/bug">www.vtk.org/bug</a> for
vtkRenderer and vtkCamera that fixed a similar clipping problem
in VTK 5.2. After examining the 5.10 source code, it looks like
the fix was never integrated into VTK's official code branch.
The page is <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.vtk.org/Bug/view.php?id=7823">http://www.vtk.org/Bug/view.php?id=7823</a>
and I noticed that its status is expired. Other users commented
in that bug report that it fixed their problems and some even
improved the fix.
