Hi Curtis,

The stereo mode initialization is done in ctkVTKAbstractRenderView.cpp
(in Slicer-build/CTK/Libs/Visualization/VTK/Widgets)
The ui is controlled by qMRMLThreeDViewControllerWidget in
Slicer/Libs/qMRMLWidgets
and the chrystalmode is set to the renderer here :
vtkMRMLViewDisplayableManager::vtkInternal::UpdateStereoType
The arguments passed to the command line are processed here:
qSlicerCoreApplication.cxx

For some reasons, the chrystal eyes mode has never been enabled
(r14862). Jc, do you recall why ?
It might be worth trying to enable it
(qMRMLThreeDViewControllerWidget.cxx:116) again and see what happens.

julien.

Hi Steve and Julien,
I spent a few minutes trying to get the CrystalEyes Stereo option to come up running in Slicer4 on my Mac. It seemed to me that some of the initialization for the stereo option is missing from the core Slicer initialization routines.

Maybe I'm barking up the wrong tree, as I haven't been deep in this for a while, but I checked the svn trunk and didn't find any machinery to initialize the SlicerApplication->SetStereoEnabled() method. I poked a bit deeper in qSlicerCoreCommandOptions and didn't find methods in qSlicerCoreCommandOptions, that I think are needed. This is where I quit because I'm probably off the path of how Slicer4 is initialized now. My slicer4 build is out-of-date, but I could work on this a bit right after Thanksgiving if it would help. Please let me know if you want me to work on the initialization . Thanks.

Ron,
I would agree after we have fixed the Crystal Eyes mode. Probably we should put a disclaimer that active stereo doesn't work for Slicer4 yet. I'll update the wiki after I hear back from Steve.

If you start Slicer4 from command line with --stereo option, the CrystalEyes option should be displayed in the stereo pulldown menu. I found the code to add and remove the crystaleyes entry is still present, but Slicer is always coming up with stereo turned off regardless of the commandline option, so CrystalEyes doesn't show on the menu (at least in my somewhat-out-of-date version).

What about changing the name of this option to "ActiveStereo" since Crystal Eyes are an old product now?

Curt,

should the 3D TV be added to the description?

    Hi Ron,
    You noticed my email to Steve and J2. I think the CrystalEyes mode is not being properly tested for during initialization. The documentation will be valid once the initialization is fixed.

    There 3D TV you asked about requires the CrystalEyes stereo mode. This is true for most (all?) of the new 3D TVs coming out. It is exciting to have affordable stereo display technology becoming available!
