AHM2012-Slicer-Architecture

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.

• Overview:
  • Each time a viewer is instantiated, it asks a factory to provide him with a DisplayableManagerGroup.
  • DisplayableManagerGroup contain a list of DisplayableManager
  • Each DisplayableManager is associated with Renderer + InteractorStyle

• DisplayableManager
  • Currently, there are two type of DisplayableManager: ThreeD and Slice DisplayableManager - Similar API.
  • Both derive from vtkMRMLAbstractDisplayableManager.
  • ThreeDDisplayableManager: deals with MRMLViewNode / ThreeDInteractorStyle
  • SliceDisplayableManager: deals with MRMLSliceNode / SliceInteractorStyle

• Factories:
  • vtkMRMLThreeDViewDisplayableManagerFactory
  • vtkMRMLSliceViewDisplayableManagerFactory
