Geometry

public class Line

extends AffineSpace

A line, as a special affine subspace of n-dimensional space, defined by a point and a vector. Points on the line can be described as a multiple of this vector, thus inducing a local coordinate system on the plane.

Constructor Detail

Line

public Line(Point origin,
            Vector x)

Constructs a new line from a point and a vector. The vectors will become the base vector for the local coordinate system.

Parameters:

origin - any point in the plane

x - any direction contained in the plane

Method Detail

getVector

public Vector getVector()

Returns the base vector for the local coordinates, as given while constructing the line.

Returns:

the direction defining the line
