Project Description

Objective

• Fix bugs exposed by using small and large scale images

Approach, Plan

• List of related bugs:
  • Fiducials disappear with large image spacing
  • Setting the unit to microns doesn't help
  • landmark size in 3D view not consistant with 2D views
• Sample data sets
  • Small - link out of date, need new sample from Murat
  • Large - 1005x1004x296 with spacing of 3x3x3.

Progress

• Investigating the base scaling assumptions for vtkSeedWidgets in 3d ctkVTKRenderView vs 2d ctkVTKSliceView
  • writing a pure CTK test case - it shows that in the default set up for the two kinds of views and mirrored seed widgets the seeds are the same size (large)
  • in Slicer, the camera in the 2d view is looking at the 2d scene from a camera distance of 1.0 while the default 3D distance is 600.0
  • in the pure CTK test case, resetting the 3D camera to a position (0,0,600) the same issues can be seen as are visible in Slicer (tiny seed in 3D, large in 2D)
