Class Angle3d

java.lang.Object

org.jzy3d.maths.Angle3d

public class Angle3d
extends Object

An Angle3d stores three 3d points, considering the angle is on the second one. An instance may return angle(), cos() and sin().

Constructor Summary

Constructors

Constructor	Description
Angle3d(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.
Angle3d(Coord3d p1, Coord3d p2, Coord3d p3)	Create an angle, described by three coordinates.

Method Summary

Modifier and Type	Method	Description
float	angle()	Computes the angle at vertex p2 between rays p1,p2 and p3,p2.
float	cos()	Computes cosinus of the angle
float	sin()	Computes the sinus of the angle, by creating a fourth point on an orthogonal direction.

Angle3d

public Angle3d(Coord3d p1,
               Coord3d p2,
               Coord3d p3)

Create an angle, described by three coordinates. The angle is supposed to be on p2

Method Detail

sin

public float sin()

Computes the sinus of the angle, by creating a fourth point on an orthogonal direction.

cos
