  11 ``` glsl
  12 // Require as many or as little as you need:
  13 #pragma glslify: snoise2 = require(glsl-noise/simplex/2d)
  14 #pragma glslify: snoise3 = require(glsl-noise/simplex/3d)
  15 #pragma glslify: snoise4 = require(glsl-noise/simplex/4d)
  16 #pragma glslify: cnoise2 = require(glsl-noise/classic/2d)
  17 #pragma glslify: cnoise3 = require(glsl-noise/classic/3d)
  18 #pragma glslify: cnoise4 = require(glsl-noise/classic/4d)
  19 #pragma glslify: pnoise2 = require(glsl-noise/periodic/2d)
  20 #pragma glslify: pnoise3 = require(glsl-noise/periodic/3d)
  21 #pragma glslify: pnoise4 = require(glsl-noise/periodic/4d)
  22
  23 attribute vec3 position;
  24
  25 // And just treat them as functions like
  26 // you normally would:
  27 void main() {
  28   gl_FragColor = vec4(snoise3(position), 1.0);
  29 }
