glsl-pi

π available at your convenience for use within glslify.

Usage

PI = require('glsl-pi')

This package exports the value of Pi as supplied by google: 3.14159265359. You can use it like so:

#pragma glslify: PI = require('glsl-pi') 
 
uniform float time;
 
void main() {
  gl_FragColor = vec4(vec3(PI * 2.0 * time), 1);
}

This is a really simple package but it saves me having to lookup/copy/paste the value every time. Also a useful alternative to using #define PI that's less leaky :)
