Hi, I’m Doug Porter from the Mayo Clinic. We have an application that we developed in-house called QREADS which runs in MS Windows and is used by our clinicians. We are looking to expand it’s capabilities from being a simple 2D medical image viewer, to including some 3D functionality. What would be …

Hello @lassoan , Does a VTK reference manual exist that contains examples of how to use functions like vtkImageSlabReslice->SetSlabThickness(thickness); How do I set the thickness and show the change in the thickness reference lines on the image. Here my code and nothing happens … void QtVTKRenderW…

[image] lassoan: We’ll try to be more helpful next time. @lassoan @jcfr @pieper , No no, I don’t expect you to have solutions to all of my dumb mistakes. My apologies for taking up so much of your time. I’m just happy that I can contribute my issues and solutions to the forum to help others.

@lassoan @pieper @Sankhesh_Jhaveri Hi, I’m trying to dynamically change the window level of images after I push button to change the W/L. vtkSmartPointer< vtkResliceImageViewer > riw; … read in and displayed images. riw->GetWindowLevel()->SetWindow(400); riw->GetWindowLevel()->SetLevel(40);| ri…

Where does this vtkResliceImageViewer come from? Do you place custom VTK actors in renderers in Slicer?

OK, I think I should be posting this is a general VTK forum. I’m not doing this in Slicer. Sorry. :neutral_face:

I just asked this because we have a mechanism to manage rendering requests in Slicer, but there is no such thing in VTK. So, the answer is different in a plain VTK render window than a render window in Slicer. For quick prototyping it might make sense try a vtkResliceImageViewer, but the current im…

To be clear, you’re saying that currently, Slicer does not have draggable handles for translating, rotating, and changing slice thickness of slice intersection widgets, correct? I could live without having handles for changing thickness; it’s probably easier and more intuitive to set thickness with …

for oblique slicing, using translation and rotation handles are most intuitive. The existing support is available through the “Reformat” widget, it can enabled using this icon: [image] [image] Once enabled, this widget is available in the 3d viewer: [image]

@lassoan I don’t think it should be too much work to move the interaction handle pipeline to a more general location. I’ll start looking into it

[image] spycolyf: Slicer does not have draggable handles for translating, rotating, and changing slice thickness of slice intersection widgets, correct? The widgets are draggable in 3D view as @jcfr showed above. In slice views, you can move slice intersection by holding down Shift key and ro…

This all sounds great. I look forward to seeing it all come together. Thanks.
