Constructor Detail

EmissionApplet.Photon

public EmissionApplet.Photon(double x,
                             double y)

Creates a new photon with random phase

Parameters:

x - The starting x coordinate

y - The starting y coordinate

EmissionApplet.Photon

public EmissionApplet.Photon(double x)

Creates a new photon with random phase and y position

Parameters:

x - The starting x coordinate

Method Detail

clone

public java.lang.Object clone()

Creates a duplicate of this photon, with the same x coordinate and phase, but a random y position.

Overrides:

clone in class java.lang.Object

paint

public void paint(java.awt.Graphics g,
                  double xscl,
                  double yscl)

Displays this photon

Parameters:

g - The Graphics surface on which to paint

xscl - Multiplier to convert simulation x coordinates to screen coordinates

yscl - Multiplier to convert simulation y coordinates to screen coordinates

update

public void update(double dt)

Advances this photon through time by the specified interval

isFinished

public boolean isFinished()

Returns:

true if this photon has been absorbed or has otherwise left the simulation, else false

die

public void die()

Indicates that this photon has been absorbed
