Code Changes

Fall 2019

1. Restructure repository of PODM3D based on Software engineering standards✔
2. Decouple Args from PODM✔
3. Create setArguments function✔
4. Create setInputImage(ImageType::Pointer)✔
5. Remove IOs from PODM✔
6. Implement a sizing function that will work as an extra rule and it will use the point indices of the tetrahedron that is tested✔
   1. Create UML diagrams to understand the code and the Meshing Procedure in general✔
   2. Create a list of functions that need to be modified to implement the extra Rule ✔
   3. Modify the created list (Extra Rule sizing Function list) of functions✔
   4. Create the following test sizing function to understand if modifications have been done correctly✔

      bool checkSizingFunction(double coordinatesOfTetrahedron**)
      {
          double volume = volume(coordinatesOfTetrahedron);
          double* baryCenter = baryCenter(coordinatesOfTetrahedron)
          
          // if x axis <= 55 and volume of tetrahedron > 10
          if (baryCenter[0] <= 55 && volume > 10)
             return true;
          else
             return false
      }
      

   5. Create the infrastructure to support Sizing Function pointer✔
   6. Incorporate Function Pointer to PODM by creating a setSizingFunction()✔
   7. Replace the test sizing function with the Adaptivity function that was created by Christos (The algorithm is described here)✔
      1. Understand that the current implementation supports negative weights✔
      2. Change the current implementation to use the minimum-maximum edge length of the element instead of its volume✔
      3. Identify an issue of checking sample points outside the image and solve it according to Christos's suggestions✔
7. Separate the interface, the IOs and the filters from PODM✔

Spring 2020

1. Create a general PODM driver✔
2. Set a warning if delta > min-spacing * min-dimension-size / 5✔
3. Set a default delta: ✔
   1. if sizing-function is off then default delta = min-spacing * min-dimension-size / 100 ✔
   2. if sizing-function is on then default delta = min-spacing * min-dimension-size / 20 ✔
4. Remove labels array if there is only 1 label of interest ✔
5. Print a warning if a label is not recovered✔
6. Add Numa flag in CmakeLists.txt ✔
7. Add binary file support ✔
8. Improve Text output ✔
9. Create label-filter to filter labels of images properly ✔
10. Remove redundant volume threadhold checks that don't contribute anything to the meshing procedure ✔
