pub struct LutBlender {
    pub dirty: bool,
    /* private fields */
}

Smoothly interpolates between LUTs when game state changes.

Fields

dirty: bool

Whether the blended LUT needs re-upload to GPU.

Implementations

impl LutBlender

pub fn new(initial: Lut3D) -> Self

pub fn blend_to(&mut self, target: Lut3D, duration: f32)

Start blending toward a new LUT over duration seconds.

pub fn set(&mut self, lut: Lut3D)

Instant cut to a new LUT (no blend).

pub fn tick(&mut self, dt: f32)

Advance the blend by dt seconds.

pub fn is_blending(&self) -> bool

Whether a blend is currently in progress.

pub fn blend_progress(&self) -> f32

Current blend progress (0.0 to 1.0).

pub fn current_lut(&self) -> &Lut3D

Get the current (possibly blended) LUT.

pub fn take_dirty(&mut self) -> bool

Consume the dirty flag. Returns true if the LUT needs re-upload.
