WebGL

WebGL trás graficos 3D para Web através da introduçãode uma API que está de acordo com OpenGL ES 2.0 que pode ser usada no HTML5 com a utilização do elemento canvas. Suporte para WebGL está presente a partir do Firefox 4 e Google Chrome 9.

Development topics

Getting started with WebGL: Como configurar um contexto com WebGL.
Adding 2D content to a WebGL context: Como renderizar simples formas planas utilizando WebGL.
Using shaders to apply color in WebGL: Veja como adicionar cor a formas usando 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.
Using extensions: How to use extensions that are available in WebGL.

Gecko notes

WebGL debugging and testing

Starting with Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7), 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.
