Function Documentation

__hostanddev__ double circDistanceSquared	(	const vector3<> &	a,
		const vector3<> &	b
	)

Return squared distance between a and b, interpreted as coordinates on a unit S1xS1xS1 embedded in R^6 i.e. sum of squares of distances between each coordinate put on a circle. This is useful for checking distances in a periodic cell safely.
