Class Angle2d

java.lang.Object
  org.jzy3d.maths.Angle2d

public class Angle2d
extends Object

An Angle2d stores three 2d points, considering the angle is on the second one. An instance may return angle(), cos() and sin()

Constructor Summary

Angle2d(Coord2d p1, Coord2d p2, Coord2d p3)
Create an angle, described by three coordinates.

Angle2d(float x1, float y1, float z1, float x2, float y2, float z2, float x3, float y3, float z3)
Create an angle, described by three points.

Method Summary

float	angle() Computes the angle
float	cos() Computes cosinus of the angle
float	sin() Computes the sinus of the angle, by creating a fourth point on an orthogonal direction.
