Hi all,
I’m working on a Qt + VTK (v8.2) application in C++ that displays three orthogonal slice views (axial, coronal, sagittal) using vtkResliceImageViewer and a shared vtkResliceCursor from axial to coronal and sagittal. I’ve successfully:
- Added orientation labels(tags)(“L/R”, “A/P”, “I/S”) via camera
GetViewUp()and camera ‐normal angle in eachvtkResliceImageViewer. - Rotated an individual slice viewer and updated its annotation labels accordingly by getting it’s
GetViewUp()and angle with rotational direction.
However, when I rotate or move the cursor in one view (e.g. via a secondary view’s vtkResliceCursorWidget or in the 3D view using vtkImagePlaneWidget), the other slice viewers do not giving their orientation labels as expected.
After moving/ rotate the reslicecursor, I tried forcing each vtkResliceImageViewer camera to re‐compute ViewUp/FocalPoint, but it doesn’t gives the expected annotations.
What I’m Looking for any suggestions from existing examples/event-driven approach or alternative ideas. Thanks in advance for any pointers, code samples, or best practices you can share!
I’m attaching the my expected labelling image for MPR…
