WebGL Extensioneer

The purpose of this library is to make it easier to work with WebGL extensions. It has two features:

  • Get extensions without having to specify a vendor prefix
  • Optionally specify an extension requirement

Usage

Include the library in your page.

<script src="webgl-extensioneer.js"></script>

Use extensions as before

    var fptex = gl.getExtension('OES_texture_float'); //will be present
    var anisotropic = gl.getExtension('EXT_texture_filter_anisotropic'); //will likely be null

Also get draft extensions

    var anisotropic = gl.getExtension('EXT_texture_filter_anisotropic', {draft:true});

API

  • getExtension(name, [specification])
  • specification: object

Specification defaults to

  • draft: false
  • approved: true
  • ref: 'browser' or 'spec', defaults to 'browser', if you set it to 'spec' you will need to regularly update your copy of the library.

The test performed is to only return extensions if they match the specification (i.e. setting approved to false will not return approved extensions)
