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.

sample

public float sample(float lambda)
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
