[mitk-users] Segmentation shift

[Nil Goyette]

Hi all,

My boss asked me to let the users decide if they want to reinit or not.
They will live with the consequence of not being aligned if they don't.
Of course I found this Loading Image... I know this is a
well-known bug and it has been repaired in
https://phabricator.mitk.org/T22619 but I have a question about this bug.

Does anyone know why there's a shift and/or how it could be repaired? I
mean, without a reinit, of course. I plan to fix it myself and it would
help me if someone gives me some hints. Thank you for your time.

Hi,

this may also have something to do with [1]? Make sure to click on "Show older changes" to see all the comments and example images/animations.

Hi Stefan,

Ouch, I now have second thoughts on fixing this! No, seriously, I'll try
it anyway but I do start with a less-than-positive attitude ;) I'm not
sure it's the same bug though. The visual is different. I can reinit
then rotate the axis as much as I want and it's ok. If I do a Global
Reinit though, I do have the bug.

I checked in PaintbrushTool::MouseMoved, there's this snippet which
surprised me:

Point3D worldCoordinates = positionEvent->GetPositionInWorld();
Point3D indexCoordinates;
m_WorkingSlice->GetGeometry()->WorldToIndex(worldCoordinates,
indexCoordinates);
MITK_DEBUG << "Mouse at W " << worldCoordinates << std::endl;
MITK_DEBUG << "Mouse at I " << indexCoordinates << std::endl;

*Reinited or not*, the world coordinates are always what I think they
will be, but the index coordinates look totally random. One of the index
is ~0.0 because it's a plane but the 2 others... I thought it would be
the same data as in my status bar "Position: <>; Index: <>" but it's
not, far from it. Should the indices be the equal? Where are these
"random" indices coming from?
