public class ConstantSpectralCurve
extends SpectralCurve

Very simple class equivalent to a constant spectral curve. Note that this is most likely physically impossible for amplitudes > 0, however this class can be handy since in practice spectral curves end up being integrated against the finite width color matching functions.

Description copied from class: SpectralCurve

This function determines the actual spectral curve data. Note that the lambda parameter is assumed to be in nanometers.

Specified by:

sample in class SpectralCurve

Parameters:

lambda - wavelength to sample in nanometers

Returns:

the value of the spectral curve at this point
