To discuss


Following today's discussion, we decided to go with OptionA described in here, it means that we would have to improve the performance of the MRML scene.

Few options:

  • Avoid direct node observation by listening for the Scene. Node could have a pointer to the Scene so that they call "InvokeEvent" on the scene. Widgets would then listen to the scene.
  • Investigate how the qMRMLSceneModel can be optimized so that one instance of the model is shared whenever possible. This would reduce the number of observations.


  • Could be renamed into Internal
  • Instead of associated the value with each node, this could be a property of the scene.
