Modularization Object Specialization
- Slicer is build on top re-usable and tested libraries.
Displayable Managers
- Displayable manager: Specialized logic handling both RenderWindow <-> MRML and RenderWindow <-> Logic interactions.
- Motivation: Have a well-designed mechanism to ...
- ...represent MRML node within a Renderer/RenderWindow.
- ... handle mouse/keyboard interaction.
- ... synchronize widget across different views.
- ... avoid to re-invent the wheel again and again.
- Usual scenario:
- Each time a viewer is instantiated, it asks a factory to provide him with a https://github.com/Slicer/Slicer/blob/master/Libs/MRML/DisplayableManager/vtkMRMLDisplayableManagerGroup.h DisplayableManagerGroup].
- DisplayableManagerGroup contain a list of DisplayableManager
- Each DisplayableManager is associated with Renderer + InteractorStyle
These factories Indeed, the API is very similar, both the (1)ThreeD and (2)Slice DisplayableManager derive from vtkMRMLAbstractDisplayableManager.
The differences are that:
(1) deals with MRMLViewNode / ThreeDInteractorStyle
(2) deals with MRMLSliceNode / SliceInteractorStyle
And again, the overhead:
- in a term of efficiency should be limited since displayable manager can be registered on demand - in term of readability should be very low. Indeed, you will have a Annotation base class for ThreeD and other one for Slice DisplayableManager. And it would be very clear to understand which object is responsible to do what .. - in term of line of code .. is more important ! But considering modern code editor and efficient c++ pre-processor/compiler .. things should go smoothly :)
