JarCastinggl-vec4
Part of a fork of @toji's gl-matrix split into smaller pieces: this package contains glMatrix.vec4.
Usage
vec4 = require('gl-vec4')
Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files.
For example, the following are equivalent:
var scale = require('gl-vec4').scale
var scale = require('gl-vec4/scale')
