Struct AutoExposure 

pub struct AutoExposure {
    pub exposure: f32,
    pub avg_luminance: f32,
    /* private fields */
}

Tracks scene luminance and computes auto-exposure.

Fields

exposure: f32

Current exposure value.

avg_luminance: f32

Smoothed average luminance (for display).

Implementations

impl AutoExposure

pub fn new() -> Self

pub fn update(&mut self, avg_lum: f32, dt: f32, params: &HdrParams)

Update with the scene’s average luminance this frame.

avg_lum: average scene luminance (log-average preferred). dt: frame delta time. params: HDR parameters.

pub fn reset(&mut self)

Reset to default state.

Trait Implementations

impl Default for AutoExposure

fn default() -> Self

Returns the “default value” for a type.
