# centroid_polygon_edges_xy

compas.geometry.centroid_polygon_edges_xy(polygon)[source]

Compute the centroid of the edges of a polygon prohected to the XY plane.

Parameters

polygon (sequence[[float, float] or [float, float, float] | compas.geometry.Point]) – A sequence of polygon point coordinates. The Z coordinates will be ignored.

Returns

[float, float, 0.0] – The XYZ coordinates of the centroid in the XY plane.

Notes

The centroid of the edges is the centroid of the midpoints of the edges, with each midpoint weighted by the length of the corresponding edge proportional to the total length of the boundary.
