Project Description

This project aims to work on VR interaction with tractograms in 3D Slicer. The goal is to develop tools that allow users to clean and annotate fiber bundles more accurately and efficiently in an immersive environment. This could support tasks such as cluster selection, labeling, or removal of outlier fibers during tractography analysis.

Objective

1. Objective A. Improve VR interaction with tractography data
2. Objective B. Improve VR interaction with the ROI box

Approach and Plan

1. Identify the source of the positional mismatch between the controller and the selected object
2. Fix VR laser-object interaction offset : Ensure the object follows the controller movement precisely without lag or offset

Progress and Next Steps

1. Users can now select and resize the ROI box in VR using the controller, which enables manual cleaning of fibers by adjusting the region of interest.
