[Insight-users] how to choose different method in run-time?

[Luis Ibanez]

Hi Wavelethe,

It is certainly possible to switch components of
the registration framework at run-time.

You are probably trying to do polymorphism with
SmartPointers while you should do it with raw
pointers.

Please post the compilation errors that you get....

Those little messages are usually useful  :-)


Thanks


   Luis
