Detailed Description

A series of 2D points. This is useful for representing either a series of points, line segments or a closed polygon. Single-precision.

void FLine2::NearestPoint	(	const FPoint2 &	Point,
		int &	iIndex,
		float &	fClosest
	)		const

Return the nearest point (of the points which make up the line). This is not the same as the closest place on the line, which may lie between the defining points.

Parameters:

Point	The input point.
iIndex	Index of the first point of the nearest line segment.
fClosest	Distance from the FLine2 to the input point.

void FLine2::NearestPoint	(	const FPoint2 &	Point,
		int &	iIndex
	)		const

A slightly faster version of NearestPoint which doesn't provide the distance to the closest point.
