WebGL brings 3D graphics to the Web by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML5 canvas elements. Support for WebGL is present in Firefox 4 and Google Chrome 9.

Development topics

Getting started with WebGL
How to set up a WebGL context.
Adding 2D content to a WebGL context
How to render simple flat shapes using WebGL.
Using shaders to apply color in WebGL
Demonstrates how to add color to shapes using shaders.
Animating objects with WebGL
Shows how to rotate and translate objects to create simple animations.
Creating 3D objects using WebGL
Shows how to create and animate a 3D object (in this case, a cube).
Using textures in WebGL
Demonstrates how to map textures onto the faces of an object.
Lighting in WebGL
How to simulate lighting effects in your WebGL context.
Animating textures in WebGL
Shows how to animate textures; in this case, by mapping an Ogg video onto the faces of a rotating cube.
WebGL best practices
Tips and suggestions to improve your WebGL content.
Cross-domain textures
Information about loading textures from domains other than the one from which your content was loaded.

Gecko notes

WebGL debugging and testing

Starting with Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0) , there are two preferences available which let you control the capabilities of WebGL for testing purposes:

webgl.min_capability_mode
A Boolean property that, when true, enables a minimum capability mode. When in this mode, WebGL is configured to only support the bare minimum feature set and capabilities required by the WebGL specification. This lets you ensure that your WebGL code will work on any device or browser, regardless of their capabilities. This is false by default.
webgl.disable_extensions
A Boolean property that, when true, disables all WebGL extensions. This is false by default.
