Hi, would it be possible to set up different ways of fiber bundle selection other than ROI?
I would be interested in using a sphere for example, simulating a simple volume of tissue activated and displaying overlapping fibers.
I did this locally by exposing
vtkExtractPolyDataGeometry* ExtractFromROI; in
vtkMRMLFiberBundleNode.h and then calling
fiberBundleNode.GetExtractFromROI().SetImplicitFunction() with a vtkSphere.
Any comments, thoughts? Can give it a try making a PR if you found this feasible.
