The new annotation module provides vtkWidgets-based tools in Slicer4.

The tools include 2D and 3D representations. While the 2D widgets only appear in one slice viewer, we want to illustrate the intersections with the other slice viewers as well.

Approach, Plan

By using mathematical projections, the position of widget intersections with different formatted plains can be calculated. We want to optimize the current and error-prune implementation.


The current implementation only sometimes work (see screenshots).
