Member Function Documentation

◆ closestPoint()

Point2 G3D::Line2D::closestPoint ( const Point2 & pt ) const

Returns the closest point on the line to point.

Referenced by distance().

◆ deserialize()

void G3D::Line2D::deserialize ( class BinaryInput & b )

◆ direction()

Vector2 G3D::Line2D::direction ( ) const

Returns the direction (or negative direction) of the line.

Referenced by fromPointAndDirection(), and Line2D().

◆ distance()

double G3D::Line2D::distance ( const Point2 & point ) const

inline

Returns the distance between point and the line.

◆ fromPointAndDirection()

static Line2D G3D::Line2D::fromPointAndDirection	(	const Point2 &	point,
		const Vector2 &	direction
	)

inlinestatic

Creates a line from a point and a (nonzero) direction.

◆ fromTwoPoints()

static Line2D G3D::Line2D::fromTwoPoints	(	const Point2 &	point1,
		const Point2 &	point2
	)

inlinestatic

Constructs a line from two (not equal) points.

◆ intersection()

Point2 G3D::Line2D::intersection ( const Line2D & otherLine ) const

Returns the point where the lines intersect.

If there is no intersection, returns a point at infinity.

◆ point()

Point2 G3D::Line2D::point ( ) const

Returns a point on the line.

Referenced by distance(), fromPointAndDirection(), and Line2D().

◆ serialize()
