Hi,
I just read the current doc for subdividing beams. The “selected
snippet“ we have in the NR there (version 2.25.28) has some very wrong
beams (first attached screenshot) and it’s not easy to collate the
output shown with the input. I propose the improved snippet
below/attached. (output in second attached screenshot)
I don’t quite understand what the `respectIncompleteBeams' property is
supposed to achieve, yet, so I’d be glad for changes on that.
Sorry I can’t turn this into a MR myself right now.
The very best regards!
Simon
