[postgis-devel] ST_MinimumBoundingRadius / Diameter

[Paul Ramsey]

In response to a user query on the list, about the actual extrema points of a set of points, we looked at the minimum bounding circle calculation, and it *almost* returns the answer… but the center and radius don’t quite give you the extrema.

CREATE OR REPLACE FUNCTION ST_MinimumBoundingRadius(geometry, OUT center geometry, OUT radius double precision)
	AS 'MODULE_PATHNAME', 'ST_MinimumBoundingRadius'
	LANGUAGE 'c' IMMUTABLE STRICT _PARALLEL
	_COST_HIGH;

I was wondering whether to add Yet Another Function or just change the signature of this function to include an ‘OUT diameter geometry’ linestring.

Thoughts?
