In the source for the vtkLineWidget there are references to being able to make the handles non-visible but still intractable by the user. I am attempting to draw SVG elements where the handles are, the same as glance and volview, but am unable to drag a handle once it has been placed. The app I’m building is using react so VolView and Glance can’t be copied 1-to-1 since they use Vue. Any help would be appreciated
An easy trick is to render the handles with opacity of 0.001.
The clean way is to play with updateRepresentationForRender. It controls the representation of handles depending if you are “rendering” or “picking”.
