org.dayflower.pathtracer.color.spectralcurve.RegularSpectralCurve

public final class RegularSpectralCurve
extends SpectralCurve

A RegularSpectralCurve is an implementation of SpectralCurve that contains regular spectral data.

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

Since:

1.0.0

Constructor Detail

RegularSpectralCurve

public RegularSpectralCurve(float lambdaMin,
                            float lambdaMax,
                            float[] spectrum)

Constructs a new RegularSpectralCurve instance.

If spectrum is null, a NullPointerException will be thrown.

The array spectrum will be cloned.

Parameters:

lambdaMin - the minimum wavelength in nanometers

lambdaMax - the maximum wavelength in nanometers

spectrum - an array with spectral data

Throws:

java.lang.NullPointerException - thrown if, and only if, spectrum is 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
