Scooping Tool for Cropping Inside the Widget about volview HOT 3 CLOSED

Inverse of the cropping widget eh? https://kitware.github.io/vtk-js/examples/ImageCroppingWidget.html

I think you could modify the VolumeMapper shader to do this. Look into the vtk.js source. Then open a thread on the vtk.js forum for guidence. https://discourse.vtk.org/c/web/9

When you have something in a vtk.js example we can help integrate into VolView.

I appreciate your response regarding the inverse cropping widget.

To clarify my request : I need a smaller widget box inside the 3D volume that allows users to see a precise portion of the 3D volume. The current cropping tool in VolView does not support this level of precision.

Specifically, I am looking for a way to:

1. Place a smaller, adjustable widget box inside the 3D volume.
2. Make the area inside this smaller widget box invisible

Sound kewl.

1. Brush up on that GLSL (teach me =)
2. checkout the vtk.js example and the cropping planes effect in the vtk.js codes
3. Ask in vtk.js discourse.
