WebGL, which stands for Web Graphics Library, is a component of web browsers that allows the browser to visualize three-dimensional graphics without any further extensions. Within this Wiki WebGL is used to provide demonstrative applets that support the reader understanding the described contents.

Activation of WebGL

In order to check whether WebGL is already activated in the current browser click on this link. In the browsers Opera and Firefox as well as in all the browsers modified out of them, WebGL is activated by default. A manual activation is usually not necessary.

Internet Explorer

To use WebGL in the Internet Explorer, please install the IEWebGL plugin. After restarting the browser you should be able to display WebGL applications.


A manual activation of WebGL is sufficient in Safari. Thereto open the developers menu under Safari->Preferences->Advanced->Show Develop Menu. Then activate WebGL by Develop->Enable WebGL.


In Firefox WebGl is usually activated by default. Otherwise perform the following steps:

  1. Type "about:config" in the adress bar of the browser to open the advanced configuration.
  2. Search for "webgl".
  3. If "webgl.disabled" is true, set this value to false by right clicking on it.
  4. Restart or reload the applet (Key F5).



If WebGL still does not work correctly, please have a look on the official WebGL-FAQ-webpage.
