Struct Lut3d 

pub struct Lut3d { /* private fields */ }

Validated three-dimensional cube, with red varying fastest.

Implementations

impl Lut3d

pub fn new( size: u16, domain_min: [f32; 3], domain_max: [f32; 3], data: Vec<[f32; 3]>, ) -> Result<Self, ValidationError>

Freezes a finite 2..=64 cube with a strictly increasing per-channel domain.

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

Parses a bounded 3D .cube, optionally preceded by a 1D shaper.

In combined files DOMAIN_MIN/MAX describe the shaper input. The cube defaults to 0..1 unless LUT_3D_INPUT_RANGE specifies another range.

pub fn size(&self) -> u16

Cube edge length.

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]]

Red-fastest immutable samples.

pub fn with_shaper(self, shaper: Lut1d) -> Self

Attaches an input shaper; its output is interpreted in the cube domain.

pub fn shaper(&self) -> Option<&Lut1d>

Optional per-channel input shaper, evaluated before tetrahedral lookup.

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

Encodes linear input, samples a look and decodes its output back to linear.

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

Tetrahedral interpolation; out-of-domain input clamps to the boundary.
