- kitware general questions to the vtk list, special features to JC

  - make sure that have a test, baseline etc.
 +
- slicer vtk git copy
 +
  - two branches of vtk git, one tracking / cherry picking branches from vtk, one patches that we want to do

  - git client for svn only works on master, not branch
 +
  - branches for each patch that want to apply
 +
  - vtk to git way of thinking: master branch, next branch, maint branch
 +
  - changes to widget to support the annotaion project (rubber band lines, click to place, etc), annot project has to drive the changes
 +
  - if some missing methods or things not exposed, both namic funded widget development and fixes to current widgets in same repository

  - vtk data is in a git repository, need to fork vtkdata

- making basic widgets work versus new widgets wishlist
 +
  - fixes can be at vtk level or slicer application

  - create pure vtk tests to show issues
 +
- getting widgets to work in 2d and 3d (some only have reps in one of the two)
 +
  - 2d handles versus 3d handles (2d are fixed to a plane)
 +
- like to do at vtk level:
 +
  - depth sorting of widgets (can't pick the "top" one, picks the first added to the renderer)
 +
  - vtk performance esp the vtkseedwidget when have lots of actors
 +
- very specific ways to interact with widgets that are opaque to users
 +
  - getting stuck in reformat widget trnaslate
 +
  - moving fids: have to be in plane perpendictular to view ray (show an axis?)
 +
  - rotate the view to constrain to surface
 +
  - widgets calling render directly too often
 +
- vtk widget designer
 +
- want to see a consistent way to tell if something can be selectged, is selected, what it's manipulating

  - how to tell something is selected

  - slicer 3.6 fine tuning + miAnnotation larger scope
 +
- new widgets
 +
  - Sudhir from Univ of Pittsburgh, endocopy apps for neurosurgeons, widget can control a cylinder width and length to quantify how much damage done to fibres
 +
    - needs the graphics, and the interaction
 +
    - use for clipping/volume rendering visib inside/out?
 +
    - field of view/cone
 +
    - cylinder widget, as it moves, it updates fibre tracking
 +
  - see transform widget in Maya
 +
  - move along a curve to snap to surface/transition animation
 +
 +
- can put a ruler widget three ways
 +
  - create  anode and put the ruler in the scene
 +
  - two fids and get a ruler
 +
  - click, get rubber bandk, click
 +
  - if when make the first click, get an overlay to show which click you're on
 +
  - can we get a Qt programmable 3d cursor? yes
 +
  - need to get at hover? state? application from widget
 +
 +
- miAnnotaion
 +
  - overlay annotation like siemens workstation, ie to pick a vtk widget (can do some of it in Qt)
 +
  - transition between 2d and 3d
 +
  - can do a lot of the 2d stuff in Qt
 +
    - what do you want to drive the 3d renderer?
 +
  - right click on a widget to get a menu to configure
 +
  - decision tree: waht do we want to do? which widget should we use? debug the widget to get it working like we wish
 +
 +
- check that
 +
 +
- vtk widget and qt level mrml nodes that are of annotation types
 +
  - architecture evolved
 +
    - synch between mrml nodes and manifestations in qt or vtk
 +
    - create a Libs/ library that is LibsMRMLRenderManager
 +
    - when you have a scene, new nodes are added, of type you're interested in, cases where there's a bulk change to the scene, app level know it's a bulk change (ie new scene), manager will be told that the mrml scene is now null, remove stuff, then given a new scene
 +
    - testing need to test on scene close, load
 +
    - on scene close, all managers told null scene
 +
    - as move to slicer4 arch, how divy up work
 +
      - jc doing prototype arch - superclass and slice node
 +
      - for 3d box, lettes, there's a node (view node now), have a manager to deal with it
 +
      - daniel working with kilian in Penn in July working up then in aug workingin bosotn, daneil and I work on how to do the translation

      - alex working with jc on superclass and then on the model

      - vtk mrml displayable manager in the lib

      - vtk mrml annotations displaybale manager

 +
      - steve proposes that htey work on the vtk level, quantify examples, look and feel debugging
 +
      - when daniel and I sit down, we work on the port
 +
    - reuse the measurements and fids modules or do the annotation rewrite?
 +
      - alex can do the ROI manager, but with the annotation roi node
 +
      - need mrml backward compatibility
 +
      - freeze the fids and measurements and get the miannotation fully functionally
 +
    - steve proposes that we change UI to Annotation, agreed

 Back to  Project Week Agenda

Session Leaders: Kilian Pohl, Nicole Aucoin

Agenda

  • Fiducials - integration into miAnnotation
  • Mouse modes
    • hover zone size versus pick zone size
    • click to place on rulers and angles as well as being able to turn that off
  • Currently used VTK Widgets
    • Debugging
  • miAnnotation status report
  • VTK Widgets being incorporated soon
    • surface model vertex inspector (contrained to surface, updating text box)
    • Use cases
  • miAnnotation status report
  • Wish list items
