Member Function Documentation

double ecl::LinearSegment::squaredDistanceFromPoint	(	const double &	x,
		const double &	y
	)		const

Distance of a point from the segment.

Returns the distance from one of the end points if it is closer than the segment itself.

TODO shift this to a standard geometry function computing the squared distance between two geometric objects.

Parameters:

x	: x coordinate of the point
y	: y-coordinate of the point

Returns:

double
