Struct AutoExposureParams 

Source 
#[repr(C)]
pub struct AutoExposureParams {
    pub lum_log2_min: f32,
    pub lum_log2_range: f32,
    pub lum_to_bin_scale: f32,
    pub _pad: f32,
}
Expand description

Input to the auto-exposure histogram kernels: the three luminance-mapping scalars then a pad rounding to 16 bytes. Matches AutoExposureParams in shaders/auto_exposure.slang.

Fields§

§lum_log2_min: f32

Lowest log2(luminance) the histogram covers.

§lum_log2_range: f32

Width of the log2(luminance) span the histogram covers (max - min).

§lum_to_bin_scale: f32

HISTOGRAM_BINS / lum_log2_range. The build kernel multiplies the centred log-luminance by this to derive a bin index.

§_pad: f32

Padding so the field layout matches the shader-side struct.
