npm install gl-lambert-material

usage

Use with gl-material to generate a compiled shader, given a gl context and constants to replace

var lambert = require('gl-lambert-material')
var material = require('gl-material')(gl, lambert, {LIGHTCOUNT: 1})

Or just get the fragment shader for use elsewhere

var fragment = require('gl-lambert-material').fragment
