LineParameters()

xms::LineParameters::LineParameters	(	double	a_slope,
		double	a_intercept
	)

Constructor from slope and intercept.

Constructor.

Parameters

[in]	a_slope	The slope. Use kVERTICAL for vertical lines.
[in]	a_intercept	The y intercept (or x intercept for vertical).
[in]	a_slope	The slope of the line. Use kVERTICAL for vertical lines.
[in]	a_intercept	The x intercept if vertical; else, the y intercept.

Member Function Documentation

Intersection()

bool xms::LineParameters::Intersection	(	const LineParameters &	a_other,
		Pt3d &	a_p
	)		const

Get the intersection point of this and another line.

Compute the intersection point of this line with another.

Parameters

[in]	a_other	The other line.
[out]	a_p	The intersection point.

Returns

false if the lines are parallel so there is no intersection.

Parameters

[in]	a_other	The other line's definition.
[out]	a_p	The intersection point (if any)

Returns

True if there is an intersection. False if the lines are parallel.

NormalThrough()

LineParameters xms::LineParameters::NormalThrough

(

const Pt3d &

a_p

)

const

Get the LineParameters for a line normal to this through a point.

Return the parameters for a line normal to this one through a point.

Parameters

[in]

a_p

The point the normal is to run through.

Returns

LineParameters for the line normal to this through a_p.

Parameters

[in]

a_p

The point through which the normal line will contain.
