MRFSurface Changelog

3.9.6 Released (Marts 30, 2021)

• Fixed a bug in unsigned distance remeshing. If a point was outside the field, crazy values would be present in the output.
• Fixed an issue where sometimes the edges of the volume would be created as iso-surfaces due to an issue with vtkSampleFunction. Now the trianglefactor (option x) works slightly differently internally.

3.9.5 Released (February 23, 2021)

• The initial iso-value when meshing unsigned distance fields can now be specified with the -I parameter. Turned out it was very difficult to compute and automatic iso-value.

3.9.4 Released (February 22, 2021)

• When meshing unsigned distance fields the initial iso-value is now =1.0 * pixel spacing instead of 0.5 * pixel spacing (that created holes)

3.9.3 Released (February 20, 2021)

• More bug fixes in unsigned distance fields.
• Can now both mesh MetaImage (mhd) and Nifti (NII) volumes. Seems that using mhd better respects the coordinate systems.

3.9.1 Released (February 8, 2021)

• Bug fixes in unsigned distance fields.
• When supplying a mesh (type 5) for unsigned distance fields a vtkCellLocator is used

3.9.0 Released (January 24, 2021)

• Initial try on unsigned distance fieldset (use -u and -p 0) (Does not work well with Laplacian prior currently).
• Meshing the true surface in the unsigned distance field is not finished but somethings gets out

3.8.0 not Released

• Padding now actually work (before a default value of 5 was always used)
• Now writes the distance field as a nifti file as well as an metaimage file

3.7.1 Released (February 4, 2020)

• Compiled with VS 2019, VTK 8.2 and GEL from GIT (snapshot december 2019)
• Bug fixes in remeshing. No longer causes NaN values in tangential relaxation
• If no extension is given on output, no output surfaces are written. Usefull in combination with option F so only the regularised distance field is written.

3.7.0 Released (January 8, 2020)

• Released as a zip file
• Compiled with VS 2017, VTK 8.2 and GEL from GIT (snapshot december 2019)
• If just given a nifti (*.nii) file as input it will extract the zero-level iso-surface and remesh it
• New parameter E can be used to specify target edge length when re-meshing (if -1 the value is automatically computed)

3.1.0 Released (February 27, 2014)

• A new parameter P can be used to control the amount of pad voxels in the distance field (default 5)

3.0.0 Released (January 27, 2014)

• x64 build only
• Multi-core in distance computations and regularisation steps
• Internal changes in optimisation steps means that results might be slightly different from results produced with previous versions

2.3.1 Released (January 14, 2013)

• Can handle reference surfaces with no active markings (no points)
• Visualises landmarks as spheres in landmark guided registration
• Improved re-texturing

2.3 Released (January 10, 2013)

• Can retexture surfaces if input files are OBJ files

2.2 Released (December 11, 2012)

• Can now read an XML settings file for doing surface alignment. Documentation will come (or ask me)
• Fixed major memory leak when computing neighbourhood statistics. Used in MRFSurface reconstruction and PCA normals.

2.1 Released (October 29, 2010)

• Includes alignment. Described in “Anatomically Plausible Surface Alignment and Reconstruction” R. Paulsen, R. Larsen. Eurographics conference on Theory and Practice of Computer Graphics 2010.
• Several new parameters:
  • m : Max number of points to use
  • N : Points per normal in normal estimation
  • D : Points used per distance estimate in a voxel
  • x : Triangle size factor (<1 fewer and larger triangles, 1> more and smaller triangles)
  • g : Apply aggresive cropping
