[IGSTK-Developers] View refactoring- Camera control

[Frank Lindseth]

Hi Andinet,

This looks very good.
Ideally the re-factoring of the ImageSliceRep. should be done first  
in order to see the needed functionality to display oblique slices in  
an optimal way for example, but I guess most things can be done using  
these methods.

Just a little note, in our present system the surgeon can "set" the  
view in the 3D scene using a tool/pointer: The view follows the tool  
(or guide wire)  in real time, and when a good view is found the view  
can be "freezed" or saved. In order to do this (just by using the  
axes of the tool) it would be nice to have a RequestSetViewDirection  
too.

And while talking about the view class re-factoring:
I'm hoping that a good synchronization scheme can be build into the  
view-class (for croshair positioning for example) :
- Synchronization between the three different views (e.g. axial,  
coronal and sagital) for a single volume.
- Synchronization between corresponding views from different volumes.
- Synchronization between the "2D and 3D display" of the same slice.
- etc.

Regards,
Frank
