=== Move Existing classes out of review ===

* rename filters?
 
* remove VTK reader / writer in favor of iowa's Mesh IO?
D. Doria has written mesh iterators for VTK. He has allowed the iterator to be a "conditional iterator" by subclassing and reimplementing the AddVertex function. It performs any test the user would like on the current vertex and the next vertex. (I.e. you can add the next vertex to the queue only if it is close enough (by any metric - distance, color, normal angle, etc) to the current vertex).
* test compilation without ITK_USE_REVIEW to check there is no left behind
The current closest equivalent with QE would be itkQuadEdgeMeshFrontIterator and seems to be confusing and perhaps less flexible.
* fix the test drivers
 
Here is D.D's superclass implementation [http://github.com/daviddoria/daviddoria-vtk/blob/VTK-ConditionalGraphIterators/Filtering/vtkGraphIterator.h github link]
 
Here is D.D's derived class: (which shows 3 different conditions) [http://github.com/daviddoria/daviddoria-vtk/blob/VTK-ConditionalGraphIterators/Infovis/vtkGraphVertexDataConditionalIterator.cxx github link]

First step of moving QE out of review
** structure
 
** Euler Operators
The basic structure as well as the Euler Operators and the helpers have been moved to Common. The filters have been moved to Algorithms and the VTKPolyData readers and wroteers to IO. The source files for the test have been moved to the corresponding directory under Testing. The tests have been removed or disabled and need further attention.
** FIlters
 
Change-Id: Ib25a00ca58c58103c184100ad51b561e5406cf72
 
oving files needed by QuadEdgeMesh tests out of review.
 
Those one felt between the cracks the first time.

Conditional Iterators

D. Doria has written mesh iterators for VTK. He has allowed the iterator to be a "conditional iterator" by subclassing and reimplementing the AddVertex function. It performs any test the user would like on the current vertex and the next vertex. (I.e. you can add the next vertex to the queue only if it is close enough (by any metric - distance, color, normal angle, etc) to the current vertex). The current closest equivalent with QE would be itkQuadEdgeMeshFrontIterator and seems to be confusing and perhaps less flexible.

Here is D.D's superclass implementation github link

Here is D.D's derived class: (which shows 3 different conditions) github link

Move Existing classes out of review - DONE - Sept 2010

  • check coverage

Review and possibly move other filters from Insight Journal

FEM Requirements

  • associate data with points and cells
  • templates are too hard and inflexible, you have to know in advance and/or create traits for each file format
  • idea #1: give me an array datastructure like in vtk.
  • idea #2: I like metadata.

Linear systems Solvers

  • TAUCS
  • SuperLU (direct)
  • CHOMOLD
  • PETsc
  • eigen

Illustrate and optimize

  • write benchmarks for data structure ( => Example)
  • profile
  • document structure building process (AddCell)
  • come up with an optimal building process (AddCell)
  • optimize code for speed
  • profil decimation and other slow filters
  • optimize code for speed

Document

  • Add a Surface Mesh part to the ITK software guide.
    • structure
    • Euler Operators
    • FIlters

recode and replace the simplex implementation with the old QEMeshWithDual design

  • write the data structure with a second point container
  • write trianglemeshtosimplexmesh (and back) filters, use them for benchmark
  • check the other filters of the simplex framework for QE compatibility
  • see if we can have the complete framework leverage QE (note, if there is no topological change, it might be slower to use QE)

Improve Simplex (M. Audette)

M. Audette's adaptation of H. Delingette's simplex mesh, where he uses T1 and T2 operators to delete specific edges in order to explicitly control surface mesh resolution (prior to controlled-resolution tetrahedralization).

The operators are on page 119 of Herve's IJCV paper General Object Reconstruction Based on Simplex Meshes which can still be found here.

M. Audettes's adaptation appears in ICCV Workshop 2005:
