Struct ColorFromSpectrum 

pub struct ColorFromSpectrum {
    pub wavelengths_nm: Vec<f64>,
    pub power: Vec<f64>,
}

CIE 1931 XYZ colour space integration from a spectral power distribution.

Uses a compact 31-point tabulation (380–780 nm, 10 nm spacing) of the standard CIE 2° observer colour matching functions.

Fields

wavelengths_nm: Vec<f64>

Wavelengths (nm) at each sample point.

power: Vec<f64>

Spectral power at each sample (arbitrary units).

Implementations

impl ColorFromSpectrum

pub fn new(wavelengths_nm: Vec<f64>, power: Vec<f64>) -> Self

Construct from paired wavelength/power vectors.

Lengths must be equal.

pub fn to_xyz(&self) -> (f64, f64, f64)

Integrate spectrum against CIE 1931 2° colour matching functions.

Returns (X, Y, Z) tristimulus values using the trapezoidal rule.

pub fn to_srgb_linear(&self) -> (f64, f64, f64)

Convert XYZ to sRGB (D65, linear, no gamma).

Values are clamped to [0, 1].

pub fn peak_wavelength(&self) -> f64

Dominant wavelength estimate: returns the wavelength with maximum power.

Trait Implementations

impl Clone for ColorFromSpectrum

fn clone(&self) -> ColorFromSpectrum

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColorFromSpectrum

fn fmt(&self, f: &mut Formatter<'_>) -> Result
