## README

# gl-vec4

[![stable](http://badges.github.io/stability-badges/dist/stable.svg)](http://github.com/badges/stability-badges)

Part of a fork of [@toji](http://github.com/toji)'s
[gl-matrix](http://github.com/toji/gl-matrix) split into smaller pieces: this
package contains `glMatrix.vec4`.

## Usage

[![NPM](https://nodei.co/npm/gl-vec4.png)](https://nodei.co/npm/gl-vec4/)

### `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:

``` javascript
var scale = require('gl-vec4').scale
var scale = require('gl-vec4/scale')
```
