Detailed Description

Defines a structure representing a point in the Cartesian space, and a function to compute the squared Euclidean distance between two points.

Function Documentation

squared_distance()

double squared_distance	(	const point	a,
		const point	b
	)

Compute the point to point distance with the euclidean rule without performing the root. E.g.: (x1 - x2)^2 + (y1 - y2)^2.

Parameters

[in]	a	The first point.
[in]	b	The second point.

Returns

The distance between 'a' and 'b'.
