Package georegression.struct.line

Class LinePolar2D_F64

java.lang.Object

georegression.struct.line.LinePolar2D_F64

All Implemented Interfaces:

Serializable

public class LinePolar2D_F64
extends Object
implements Serializable

Defines a line in 2D space based upon the distance of its closest point to the origin and the angle of a line from the origin to that point. Also referred to as the polar line equation.

Equation:
x*cos(θ) + y*sin(θ) = r
where r is the distance from the closest point on the line to the origin, and θ is an angle tangent to the line.
