Revision Content

WebGL tuo 3D-grafiikan Webbin esittelemällä sovellusohjelmointirajapinnan (API), joka on läheisesti yhteensovpiva HTML5 canvas-elementissä käytetttävän OpenGL ES 2.0 -määrittelyn kanssa. Tuki WebGL:lle on nykyisin Firefox 4+ -selaimissa, Google Chrome 9+ -selaimissa, Opera 12+ -selaimissa ja Safari 5.1+ -selaimissa.

Kehitysaiheita

Kuinka aloittaa WebGL-asennus
Kuinka asettaa WebGL-ympäristö.
Lisätään 2D-sisältöä WebGL-ympäristöön
Kuinka renderoidaan yksinkertaisia litteitä muotoja WebGL:tä käyttäen.
Varjostimien käyttäminen värien toteuttamisessa WebGL:ssä
Esittelee, kuinka lisätä väri varjoja käyttäviin muotoihin.
Objektien animointi WebGL:ssä
Näyttää kuin kiertää ja muuntaa objekteja yksinkertaisten animaatioiden luomiseksi.
3D-objektien luominen käyttäen WebGL:ää
Näyttää, kuinka luoda ja animoida 3D-objekti (tässä tapauskessa kuutio).
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.
Parhaimmat WebGL-käytännöt
Vihjeitä ja suosituksia WebGL-sisällön luomiseksi.
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.
WebGL-spesifikaatio
WebGL-spesifikaatio.
Khronos WebGL site
The main web site for WebGL at the Khronos Group.
Learning WebGL
A site with tutorials on how to use WebGL.
The WebGL Cookbook
A web site with handy recipes for writing WebGL code.
Planet WebGL
A feed aggregator for people involved in the WebGL community.
ewgl-matrices
A blazing fast matrix library for WebGL
glMatrix
JavaScript Matrix and Vector library for High Performance WebGL apps
mjs
A JavaScript vector and matrix math library, optimized for WebGL usage.
Sylvester
An open source library for manipulating vectors and matrices. Not optimized for WebGL but extremely robust.
WebGL playground
An online tool for creating and sharing WebGL projects. Good for quick prototyping and experimenting.

Gecko notes

WebGL debugging and testing

Starting with Gecko 10.0 {{geckoRelease("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.
