Expand description

How a light’s intensity varies over time.

Variants§

§

Constant

Constant: no variation.

§

Pulse

Sine wave: intensity oscillates at frequency Hz.

Fields

§frequency: f32

§min_intensity: f32

§max_intensity: f32

§

Flicker

Perlin-noise flicker (torch-like).

Fields

§speed: f32

§depth: f32

§

Strobe

Strobe: alternates fully on/off at frequency Hz.

Fields

§frequency: f32

§

Fade

Fade from start to end over duration seconds.

Fields

§start: f32

§end: f32

§duration: f32

§

Math

Driven by a MathFunction: maps f(t) → [0,1] → intensity.

Fields

§func: MathFunction

§base_intensity: f32

§amplitude: f32

§

ColorCycle

Color-shifting animation: cycles through hue over time.

Fields

§speed: f32

§saturation: f32

§value: f32

§

Heartbeat

Heartbeat: two fast pulses per beat.

Fields

§bpm: f32

§base_intensity: f32

Implementations§

Source §

impl LightAnimation

Source

pub fn intensity_factor(&self, t: f32, id_seed: u32) -> f32

Evaluate intensity multiplier at time t in seconds.

Source

pub fn color_at(&self, t: f32, base_color: Vec3) -> Vec3

Evaluate color at time t. Returns Some(color) only for color-animating modes.
