Objective

Create a pluggable structure for managing MRML<-->VTK Rendering and Widget interactions in the context of Slicer4. This include mapping MRML annotation nodes to and from vtkWidgets, mapping vtkMRMLModelNode and hierarchies to vtkActors/vtkMappers.

Others:

• Fidicials (all annotations)
• ROIs
• VolumeRendering
• Module-specific rendering (should be possible for loadable module to register a class that maps MRML nodes to-from elements in the vtkRenderWindow

Approach, Plan

Create a vtkSlicerManagerFactory and vtkSlicerAbstractManager. The vtkSlicerAbstractManager is parameterized by a vtkRenderWindow and is subclassed for each purpose. The vtkSlicerManagerFactory holds a registry of manager types so that when a new 3D Viewer is create, a set of managers is associated with the viewer.

Loadable modules should be able to access to ManagerFactory and register custom manager types to handle their custom nodes.

Progress

• created architecture and coded initial implementation for vtkMRMLDisplayableManager library including
  • vtkMRMLDisplayableManagerFactory class
  • vtkMRMLAbstractDisplayableManager class
  • vtkMRMLModelDisplayableManager
