Module: Platinum - Geometry Primitives
Topic: Mistake
Message:

@brebenelmihnea any update on this?

btw, there are alternative implementations that may be simpler to implement (e.g., https://github.com/bqi343/cp-notebook/blob/08e3d0d722584442bd38280251d5e65f7ac61612/Implementations/content/geometry%20(13)/Polygons/InPolygon.h#L5)
