Node focus in views

Key Investigators

Presenter location: In-person

Project Description

3D software applications often provide feedback mechanisms for selecting objects and showing users which objects they have selected, or are interacting with. This allows some visualizations to be hidden when the object is not in focus.


This project aims to implement a similar node selection system in 3D Slicer, allowing users to:

If you would like to offer suggestions or feedback on the current prototype, then come see me in-person.

Approach and Plan

  1. Continue development of the node focus infrastructure.
  2. Get feedback from hands-on use to better improve the implementation.
  3. Improve visualization and performance.

Progress and Next Steps

  1. Prototype implementation can be found here: https://github.com/Sunderlandkyl/Slicer/tree/focus_node_prototype
  2. Improve rendering of volumes + hard selection.
  3. Implement picking of node types other than markups.


Example showing segmentations:

Atlas node focus

Example showing markups:

Markups node focus

Example showing models using a combobox:
