Struct HableFilmic 

pub struct HableFilmic;

John Hable’s filmic curve from GDC 2010 (“Uncharted 2”). Identical math to libultrahdr’s reference implementation and the original GDC 2010 paper.

Parameter-free, monotonic on [0, ∞), gentle shoulder, no luminance calibration required. A reasonable zero-config default for HDR encoding when no scene metadata (PQ peak, HLG peak) is available to pick a more principled curve like Bt2408Yrgb or Bt2446C.

Output is clamped to [0, 1].

Implementations

impl HableFilmic

pub const fn new() -> HableFilmic
