Home < Novel Hexahedral Meshing Algorithms

Objective:

  • Develop and integrate novel hexahedral meshing algorithms into the NA-MIC kit

Progress:

  • Base projection algorithms have been developed and will be integrated into the toolkit. The algorithms have been implemented in KWWidgets in IaFeMesh to simplify integration into Slicer3.
  • The base code and algorithms have been brought into Slicer3 for integration within the GUI and MRML. Curt Lisle has been working on a this integration.
    1. The sort term goal is to get a single editable bounding box working within Slicer3 for the next release.
    2. Projection based morphing and mesh interpolation will be required.
    3. Include export to Abaqus format
  • Develop mapped meshing techniques that include an FE based solution using ITK that registers a template mesh with a subject specific surface.
  • Building of meshing code has now been turned on by default for the latest Slicer3 release.
    • Fully support all bounding box editing options
      1. Vertex manipulation
      2. Add
      3. Delete
      4. Split
      5. Merge
      6. Extrude
      7. Face manipulation
    • Allow the user to undo and redo operations - This should be supported by the inherent logic in the MRML scene description.
    • Extract mesh material properties from the images
    • Export to Abaqus format

To Do:

  • Develop testing modules using the GUI framework being developed by Kitware.
  • Refine integration with Slicer. This is mainly related to the handling of data objects between Slicer3 and the meshing module interface.
