KWScene/Documentation/May-June Schedule

4 weeks before NAMIC Summer Project Week

End-goal: convincing demo for JHU (Mike Bowers) at NAMIC Summer Project Week

Planned use-cases under Paraview

• Visualize scalar, vector, tensor surfaces: byu, vtp (xml).
• Visualize scalar, vector, tensor volumes: Analyze, vti (xml).
• Visualize landmarks. How to deal with annotations to be discussed at NAMIC.
• Adapt an ITK program to a VTK plug-in running on Paraview. At NAMIC, try running with Beltrami filter developed by Mike Bowers of JHU.
• Results of ITK-based processing should be storable in a scene and visualizable, which in turn can be saved to mrml file.
• Load a MRML scene containing two or more objects whose relative position is defined by a MRML Transform Node.
  • Two images that were registered inside slicer
  • One image and a surface model.

05/21 - 05/28 planning

• 05/21-28 Michel - wrap up new RepresentationNode (derived from ShapelessNode) and Slice, CompositeSlice, SurfaceDisplay, ImageDisplay nodes derived from it. Refactor Parser to populate these representation nodes, a vector to pointers of which is stored in each shaped node (SurfaceNode, ImageNode) and finish Writer classes.

Test should be able to take a mrml node that contains Model, ModelDisplay, ModelStorage, Volume, VolumeDisplay, VolumeStorage, Slice, CompositeSlice, populate a scene, and save the scene in a manner that preserves these node types (~3 days).

• • Done, but order not preserved (uses a map, which sorts alphabetically during input). Processing of nodes by Paraview should be order insensitive.
• 05/24-28 Julien - wrap up and demonstrate visualization of vti and vtp files, both directly and via a mrml file. Review status of Analyze, byu, again directly and via mrml (~2 days).
• 05/24-28 Andinet - wrap up vti (xml image) ITK generator (2 days).
• 05/21-28 Luis - resume work on KWScene transform, focus on bringing transformations into ParaView. (depart from the attempt to have VTK transforms implemented by subverting OpenGL into doing our bidding).

05/31 - 06/04 planning

• 05/31 - 06/04 Michel - implement Landmark Node & ITK/VTK Generator, based on .lmk file format. http://www.cis.jhu.edu/software/lddmm-landmark/lmkformat.html (2-3 days)
  • core classes, parser classes done; need writer classes as well as VTK/ITK generator classes that can open .lmk file. 1-2 days more.
• 05/31 - 06/04 Julien - basic visualization of tri-planar view of volume, based on mrml file. KWScene stores VolumeArchetypeStorage, Volume, VolumeDisplay, Slice and SliceComposite mrml nodes, and sets pointers to related nodes. (2-3 days)
• 05/31 - 06/04 Andinet - wrap up vti (xml image) ITK generator & begin vtp (xml surface) ITK generator (2-3 days)
• 05/31 - 06/01 Luis - working on Transforms (2 days) [traveling between 06/01-06/04]

06/07 - 06/11 planning

• 06/07 - 06/11 Michel - Test ITK-program to VTK-plugin mechanism in Paraview (2-3 days)
• 06/07 - 06/11 Julien - Wrap up slice display, demonstrate compatibility with Slicer.
  • Demos 06/11: image - mhd; surface - vtk; operations need to preserve VTK class.
• 06/07 - 06/11 Andinet - wrap up vtp (xml surface) ITK generator (2-3 days)
• 06/07 - 06/11 Luis - Working on Transforms (3 days)

06/14 - 06/18 planning

• 06/14 - 06/18 Michel - Understand Paraview and prepare to assist plugin development at NAMIC Week; basic wiki documentation & Doxygen.
• 06/14 - 06/18 Julien - Wrap up workflow from previous week. Paraview side: Simple example of a VTK-plugin of ITK-based filtering (2-3 days)
• 06/14 - 06/18 Andinet - VTK-ITK side: Simple example of a VTK-plugin of ITK-based filtering (2-3 days) InsightApplications/Auxiliary/vtk

(eg itk::RecursiveGaussianImageFilter: quick algorithm, visible result...)

• 06/14 - 06/18 Luis - Working on Transforms (2 days)
