π available at your convenience for use within glslify.
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 :)
