webgl-context


Grabs a WebGLRenderingContext, returning null if it doesn't exist. Similar to 2d-context.

``js
//get a webgl context, will be null if not found
var gl = require('webgl-context')()

if (gl) {
document.body.appendChild(gl.canvas)
//do something...
}
`

Or, with options:

`js
//or with optional settings...
var gl = require('webgl-context')({
canvas: canvas, //the canvas DOM element to use
width: 400, //resizes the canvas..
height: 200,
antialias: true //can specify custom attributes here
})
`

Usage

![NPM](https://nodei.co/npm/webgl-context/)

#### ctx = require('webgl-context')([opt])

Gets a new canvas context with optional parameters:

- canvas a canvas element to use, otherwise creates a new element
- width a width to set, otherwise no change
- height a height to set, otherwise no change
- other attributes are passed to the getContext call, like alpha and antialias

You can then get a reference of the canvas element with ctx.canvas`.
