babel-plugin-glsl

babel-plugin-glsl

A Babel plugin to process GLSL code with glslify, a module system for GLSL.

Example

In

const fragmentShader = glsl`
  #pragma glslify: random = require(glsl-random)

  void main () {
    float brightness = random(gl_FragCoord.xy / resolution.xy);
    gl_FragColor = vec4(vec3(brightness), 1.0);
  }
`;

Out

const fragmentShader = `
  #define GLSLIFY 1

  highp float random(vec2 co) {
    highp float a = 12.9898;
    highp float b = 78.233;
    highp float c = 43758.5453;
    highp float dt= dot(co.xy, vec2(a,b));
    highp float sn= mod(dt, 3.14);
    return fract(sin(sn) * c);
  }

  void main () {
    float brightness = random(gl_FragCoord.xy / resolution.xy);
    gl_FragColor = vec4(vec3(brightness), 1.0);
  }
`;
