glsl-tone-map

A collection of tone mapping functions available both as ES modules strings and as GLSL files for use with glslify. Mostly taken from here and here.

Installation

npm install glsl-tone-map

Usage

ESM

import * as glslToneMap from "glsl-tone-map";

const shader = /* glsl */ `
${glslToneMap.AGX}
${glslToneMap.NEUTRAL}
${glslToneMap.ACES}
${glslToneMap.FILMIC}
${glslToneMap.LOTTES}
${glslToneMap.REINHARD}
${glslToneMap.REINHARD2}
${glslToneMap.UCHIMURA}
${glslToneMap.UNCHARTED2}
${glslToneMap.UNREAL}

void main() {
  // ...
  color.rgb = agx(color.rgb);
  color.rgb = neutral(color.rgb);
  color.rgb = aces(color.rgb);
  color.rgb = filmic(color.rgb);
  color.rgb = lottes(color.rgb);
  color.rgb = reinhard(color.rgb);
  color.rgb = reinhard2(color.rgb);
  color.rgb = uchimura(color.rgb);
  color.rgb = uncharted2(color.rgb);
  color.rgb = unreal(color.rgb);
