[GoFigure2-developers] VTK 6.0

[Kishore Mosaliganti]

Ok, I jusr pushed a new branch called feature_ITKv4VTK6Integration off the feature_ITKv4Integration branch. In the new branch, I made all the changes for making it compatible to VTK 6.0.

There is one small CMake problem in that it is not linking to vtkLSM library. Can you fix that? It should take you 2 min. Everything else is all set.

Hi Arnaud,

Do you know what is the role of vtkTypeRevisionMacro() and vtkCxxRevisionMacro() before the definition of a class ? It seems to cause problems in VTK 6.0 and a lot of my code has it.

Hi all,

The branch compiles correctly now with vtk 6.0. But it does not produce any visualization -- only dark screen. Some minor bugs have been introduced into the pipeline.

Have you fixed the issue with vtkLSM ?

[Kishore Mosaliganti]

Hi Arnaud,

I sorted the vtkLSM issue in the second commit of the branch by adding it to the target link libraries. 

However, the images are not being loaded, only a black screen exists upon opening GF2. It seems like somewhere an Update() is required. I will try to step through my changes and see where that is happening.

Cool!

Have you figured out the bug when using the one click segmentation?

[Kishore Mosaliganti]

Hi Arnaud,

I will look at the one-click problem on master branch today and get back to you. It might not be a GF2 bug since it was working before my Ubuntu 12.04 update.

Hi Arnaud,

It seems like Master is failing in release mode only and works fine in debug mode.

To make sure everything is right, I recompiled ITK 3.20.1 and VTK 5.8 in release mode from scratch. The output at at the command line is:

QAbstractItemView::setSelectionModel() failed: Trying to set a selection model, which works on a different model than the view.
QAbstractItemView::setSelectionModel() failed: Trying to set a selection model, which works on a different model than the view.
QAbstractItemView::setSelectionModel() failed: Trying to set a selection model, which works on a different model than the view.
Segmentation fault (core dumped)

The crash happens when I use one-click segmentation. I used Qt debugger to further narrow down the location.

Any ideas?

Good idea! I am using Qt 4.8.1. I will try with a compiled earlier version and let you know.

Hi Kishore,

Which version of Qt are you using?
You might want to try to recompile vtk and GoFigure with an older version of Qt...

Hi guys,

It seems like there are two options to set this right:

1. Merge feature_ITKv4Integration to master and develop and use ITKv4. Both the branches are doing well.

2. Fix the bug with Qt 4.8 with current master and develop branches using ITKv3. Most likely it is some library error.

If we want to do 1, should I have to test this out on Windows and MacOS systems first? Do you guys mind trying it on your systems if you have the time.

I remember we had a similar issue with Qt 4.8 on OSX Lion a few month ago...

[Kishore Mosaliganti]

To further clarify on option 2, it is only the release configurations of master and develop branches that crash. The debug versions are doing fine.
