[Insight-users] ITK and Amira

[Luis Ibanez]

Hi Peter,

The simplest way of managing this kind of adaptors is to
use the facade pattern:
http://en.wikipedia.org/wiki/Facade_pattern


A) you create a facade C++ class:

              myAmiraITKExtension

     with files

              myAmiraITKExtension.h
              myAmiraITKExtension.cxx


      That you manage normally from the GNUMakefiles genereated from
      Amira.


B) Then you write another C++ class:

              myAmiraITKExtensionImplementation

     with files

              myAmiraITKExtensionImplementation.h
              myAmiraITKExtensionImplementation.cxx


      That you configure with CMake in order to create
      a static library.


C) In  myAmiraITKExtension.h you forward declare
    myAmiraITKExtensionImplementation as a pointer
    and make sure that you DO NOT include any ITK
    header, and DO NOT include either the header
    myAmiraITKExtensionImplementation.h


D) In  myAmiraITKExtension.cxx you include the
    myAmiraITKExtensionImplementation.h header
    and instantiate the class myAmiraITKExtensionImplementation.


F) At this point, you can simply add an ITK pipeline to
    myAmiraITKExtensionImplementation, and Amira doesn't
    need to know about it, nor about the process used
    for configuring the library with CMake.



   Regards,



       Luis
