I want to determine a polygon's visual centre point in 3D space. Doing some initial research, I've come across this article by Vladimir Agafonkin describing one potential algorithm. However, the example implementations rely on other libraries and are tailored specifically for 2D space.
While rudimentary approaches (average, centroid, bounding box centre, etc.) work for simpler shapes such as regular convex polygons, it certainly gets hairier with irregular or concave polygons.
To help illustrate what I'm after, take these 2 example polygons:
The point that I'm interested in would be the red dot (as a Vector3 [x, y, z]).
Is there a way to achieve this in 3D space using vanilla Python (no third party modules)? Or another algorithm one of you have come across in your travels that may apply to this situation — or at the very least point me in the right direction?
