• Rework to not require QT
• Poll for events in a separate thread (vtkRenderWindowInteractor.processEvents)
• Store windows in a module level list/dict
• Implement close()

Optional:

• Implement adding/removing of objects to/from a existing window

Looks very useful. I've been making use of https://github.com/jmwright/cadquery-png-plugin for similar capabilities but it would be desirable to have this PNG export in CQ directly.

That optional tasks in the comment at the top reminds me a bit of the Assembly.remove method we chatted about. Would that be another way of achieving the same image if we could pop objects out of the assembly

Many thanks for this feature, looking forward to making use of it

PNG export was implemented in #1759 .
