Home < Documentation < Labs < Surface Toolbox update


Overview

As part of the SALT project we would like to revamp some of the existing functionality in MeshMath into the SurfaceToolbox. We will be hiring a summer intern to work on this over a couple of months this summer.

Team

  • JC Fillon-Robin
  • Bea Paniagua
  • Jared Vicory
  • Andras Lasso
  • Martin Styner
  • Benjamin Wilson (Kitware Summer intern 2019)

Definitions

  • KWMeshVisu: Legacy mesh viewer from the Styner Lab.
  • Types of Mesh Operations:
    • Multiple Mesh (2+)
    • Single Mesh
    • MeshToVolume
    • MeshScalar to Mesh
    • MeshScalar to MeshScalar
    • MeshScalar Operation
    • Mutliple MeshScalar

Initial discussions

We will be potentially implementing individual CLIs for each functionality in MeshMath, and those will be plugged into the Surface Toolbox.

We would like to add a parameter node so if you save the scene and reload then all the node and parameter selections that you have made are not lost Enclose all functionality in C++ little CLIs that can be called from the python infrastructure, so they can be used from any modules Do the same thing for the functionality in MeshMath, creating independent CLIs and modules

listPointData lists info about all the VTK point Data in the vtk file SingleMesh Check.svg Probably keep, but functionality slightly overlaps with other functionality that will be improved when ported. Will revisit later.
pointDataOP threshold or subtract data SingleMesh Check.svg (Work in Progress)
translateMesh translates a mesh for a given amount SingleMesh Check.svg (Implemented)
lookupPointData substitutes scalar values in a given scalar field based on an input lookup SingleMesh Check.svg (Work in Progress)
volumePolyData provides volume count for the PolyData through the std output. NOTE: Only in closed surfaces. SingleMesh Check.svg (Work in Progress) Keep altogether with the surface area functionality described above (vtkMassProperties)

Path forward

Using vtkMRMLScriptedModuleNode

This node is particularly useful as it helps store parameters used for computation. See vtkMRMLScriptedModuleNode.h

The main idea is to have a parameter node selector allowing to choose between different set of parameters.

For an example of use in a scripted module. See Modules/Scripted/SegmentStatistics/SegmentStatistics.py

Testing data
