<font face="Arial, Helvetica, sans-serif">Hello<br>
I am triying to deform an itk::Mesh using itk::DeformableMesh3DFilter and am having a problem.<br>
If I generate my itk::Mesh using itk::SphereMeshSource then the DeformableMesh 3DFilter runs fine.<br>
<br>
If I write the mesh generated by itk::SphereMeshSource to vtkPolyData Format using itk::VTKPolyDataWriter and then read it in using itk::VTKPolyDataReader then<br>
the DeformableMesh3DFilter throws an exception. The exception is due to CellDataContainer being a null pointer and the CellData being empty.<br>
<br>
If i then try to assign CellData to the itk::Mesh myself by iterating over the number of cells and using ->SetCellData, then<br>
at some point in the running of itk::DeformableMesh3DFilter the filter deletes the CellData and the program crashes. <br>
<br>
This will become important for me since i would eventually like to take triangle meshes in .vtk format and use them as input to the itk::DeformableMesh3DFilter.<br>
<br>
So my questions are:<br>
1) What is the CellData that is assigned when a mesh is generated using itk::SphereMeshSource? The documentation states:" </font>More parameters are added to make the sphere mesh have global and local deform ability.<font face="Arial, Helvetica, sans-serif">" but<br>
fails to explain what those parameters are and how they are set.<br>
<br>
2) Any ideas why the CellData that i manually set is being deleted by the itk::DeformableMesh3DFilter? Even if i know the answer to 1) and manually set the CellData, it is going to be deleted by the itk::DeformableMesh3DFilter<br>
Is there other data or flags being set?<br>
<br>
