[Insight-users] Wrapping Custom Classes

[Luis Ibanez]

Hi Carlos,

1) Yes, you can wrap custom classes without having to touch
     the ITK source tree.

     Please look at

              InsightApplications/ConnectVTKITK

    for an example on how to do this.  The two classes there
    are intended to connect VTK and ITK pipelines and the
    CMakeLists.txt file is configured for wrapping these two
    classes.


2)  Do you intend to use an optimization process for computing
     this plane ?

    In this case, yes, you need to create a cost function that derives
    from itk::SingleValuedCostFucntion.   The array of parameters
    for the  cost function will be the coefficients of the plane.



Please let us know if you have further questions.


    Thanks


         Luis
