- update to 4.7.2:
The significant update for this release is that it is compatible with the
latest VTK-9.x series and is known to work with VTK 9.0.1 from PyPI. The
picker UI has changed to no longer pop up a UI window but instead show the
picked attributes on the render window directly. The original picker UI is now
available on the scene's UI in a separate "Picker" tab. This is accessible
from either the pipeline view when one edits the properties of a scene or
through the "configure scene" gear icon on the scene window toolbar.
