Class Angles

java.lang.Object
  optics.Angles

public class Angles
extends java.lang.Object

Class to implement the two director angles theta and psi

Field Summary

double	psi The psi angle
double	theta The theta angle

Constructor Summary

Angles()

Angles(Angles a)
Form a Angles object with angle taken from the specifying Angles object

Angles(Director u)
Form a Angles object specifing a Director

Angles(double theta)
Form a Angles object specifing of the theta angle, the psi defaulting to zero.

Angles(double theta, double psi)
Form a Angles object specifing both angle in radians.

Method Summary

Angles	clone() Method to clone the current Angles object.
double	getPsi() Method to get the psi angle wrt to z-axis
double	getPsiDegrees() Method to get the psi angle wrt to z-axis in degress
double	getTheta() Method to get the theta angle wrt to z-axis
