How to find faces pointing inward with a python script which uses Blender sdk?
Normally I trigger "backface culling" and select points/face by visual inspection:
Then I delete the selected geometry, which leaves a hole:
And finally I do a F-fill:
In short, I'm asking if there's a way to select backfaces without a visual check, using python. There's an answer here by Zeffii, but it is related to a camera view, while I'm looking for something topology-related... Thank you.
EDIT: how I did it.
Open the blend, and select the partial sphere:
Now enter select edges, the Select non manifold (ctlr-alt-shift-M), then F or Alt-F for filling it. The result is:
How to heal that?
