Polygon.centroid()
See original GitHub issueDescribe the bug
Polygon.centroid returns a strange value for a polygon with 4 points that is self interesecting (see image),
Using the same points (of the polygon), but cycled differently we get a polygon that is more conventional…
To Reproduce Steps to reproduce the behavior:
- Python script:
from compas.geometry.primitives import Polygon, Point
polygon1 = Polygon([Point(0.000, -5.536, 1977.967), Point(0.000, 144.352, -0.000), Point(0.000, -148.968, -0.000), Point(0.000, 264.624, 1977.967)])
polygon2 = Polygon([Point(0.000, 144.352, -0.000), Point(0.000, 264.624, 1977.967), Point(0.000, -5.536, 1977.967), Point(0.000, -148.968, -0.000)])
print(polygon1.centroid)
print(polygon2.centroid)
>>>>Point(0.000, -471.050, -7031.803)
>>>>Point(0.000, 62.715, 975.434)
Expected behavior I would expect them to have the same centroid.

@gonzalocasas needs to be discussed in the next dev meeting…
will leave it open as a reminder that the current implementation can lead to unexpected results 😃
