org.dayflower.pathtracer.color.spectralcurve.IrregularSpectralCurve

public final class IrregularSpectralCurve
extends SpectralCurve

An IrregularSpectralCurve is an implementation of SpectralCurve that contains irregular spectral data.

This class is immutable and therefore suitable for concurrent use without external synchronization.

Since:

1.0.0

Constructor Detail

IrregularSpectralCurve

public IrregularSpectralCurve(float[] amplitudes,
                              float[] wavelengths)

Constructs a new IrregularSpectralCurve instance.

If either amplitudes or wavelengths are null, a NullPointerException will be thrown.

Both arrays amplitudes and wavelengths will be cloned.

Parameters:

amplitudes - an array with amplitudes

wavelengths - an array with wavelengths in nanometers

Throws:

java.lang.NullPointerException - thrown if, and only if, either amplitudes or wavelengths are null

Method Detail

sample

public float sample(float lambda)

Returns a sample based on the wavelength lambda in nanometers.

Specified by:

sample in class SpectralCurve

Parameters:

lambda - the wavelength in nanometers

Returns:

a sample based on the wavelength lambda in nanometers
