Struct Lut1d 

pub struct Lut1d { /* private fields */ }

Immutable per-channel linear shaper with 2..=65536 samples.

use motion_core::{Cdl, ColorWheels, Lut1d};
let shaper = Lut1d::new([0.0; 3], [16.0; 3], vec![[0.0; 3], [0.8; 3], [1.0; 3]])?;
let look = ColorWheels::default().bake(2, 1.0, Cdl::default())?.with_shaper(shaper);
assert!((look.sample([8.0; 3])[0] - 0.8).abs() < 1e-6);

Implementations

impl Lut1d

pub fn new( domain_min: [f32; 3], domain_max: [f32; 3], data: Vec<[f32; 3]>, ) -> Result<Self, ValidationError>

Freezes finite samples and strictly increasing per-channel input domains.

pub fn domain_min(&self) -> [f32; 3]

Minimum input domain.

pub fn domain_max(&self) -> [f32; 3]

Maximum input domain.

pub fn data(&self) -> &[[f32; 3]]

Immutable RGB rows, one sample per channel in each row.

pub fn from_cube(text: &str) -> Result<Self, ValidationError>

Parses a standalone 1D .cube; combined files belong to Lut3d::from_cube.

pub fn sample(&self, rgb: [f32; 3]) -> [f32; 3]

Samples channels independently, clamping input but not output.
