I’m trying to create a “Recalculate Normals” (similar to the operator bpy.ops.mesh.normals_make_consistent()) with geometry nodes that works as precisely as the operator for various mesh topologies.
Here’s the thread I posted on Blender Artists for any one interested:
Can someone explain me the algorithm / logic used by the operator or point me to documentation?
Or better, knows how to implement this in Geonodes…
Or even better yet, tell me that a Recalculate Normals node is planned in the development!
This is verging on user-support / feature request, but it’s an interesting topic that I’ve wondered about myself too, so I will leave it for now-- just keep that in mind in the future.
The operator is documented here: Normals — Blender Manual
The code implementing the operation is in bmo_recalc_face_normals_exec in bmo_normals.c
