Constructor Detail

Singlet2D

public Singlet2D(OpticalSurface f,
                 OpticalSurface b)

Form a Singlet2D object with a specified front and back OpticalSurface.

The front surface must be REFRACTING and the refractive index between the surfaces must be defined (and NOT Air).

Parameters:

f - the front OpticalSurface

b - the back OpticalSurface

Method Detail

setIndexColour

public void setIndexColour(java.awt.Color c)

Method to set/reset the index colour being the colour used to represent the ``glass''. By defaults this is set the Color returned by Colour.RefractiveIndexColour(double) at wavelengths Constants.GREEN.

Parameters:

c - the Color to to the glass.

See Also:

Colour.RefractiveIndexColour(double)

getBounds

public java.awt.geom.Rectangle2D getBounds()

Method to get the bounds of the lens being a box which enclosed the lens in global coordinates.

Specified by:

getBounds in interface Diagram2DComponent

Returns:

Rectangle2D the bounds

draw

public void draw(java.awt.Graphics2D g)

Method to actually draw the lens in a Graphics2D context. The surfaces are draw using quadric curves with the control points set by the on-axis and edge points. The actual curve does not depend only curve type so may be slightly out for highly curves surfaces. This is only a drawing artifact and does not affect the actual ray calculations.

Specified by:

draw in interface Diagram2DComponent

Parameters:

g - the Graphics2D context
