Color shader functions

These methods are to be used with glslify.

Usage

uniform sampler2D tInput;
uniform vec2 resolution;
uniform float time;
 
varying vec2 vUv;
 
// Import the methods you need 
#pragma glslify: vignette = require(color-shader-functions/vignette) 
#pragma glslify: bsc = require(color-shader-functions/bsc) 
#pragma glslify: film = require(color-shader-functions/film) 
 
void main() {
  vec4 color = texture2D(tInput, vUv);
 
  color = vignette(color, 1.4, 2.3, resolution);
  color = bsc(color, 0.8, 0.8, 0.9);
  color = film(color, vUv, time, 2048.0, 0.4, 0.3);
 
  gl_FragColor = color;
}
