====== WebGL help ======

To display molecules in 3D in [[dockingvina|docking]], we use a technology built into the latest browsers called WebGL. Unfortunately, at the moment this is not available on every browser, and even then, in some cases it must be enabled separately.

To quickly verify that your browser supports WebGL, [[http://get.webgl.org/|click here]]

===== Supported Browsers =====

We recommend you use one of the following browsers to access these features:

  * [[http://www.mozilla.org/en-US/firefox/new/|Firefox]] 4 or later
  * [[https://www.google.com/intl/en/chrome/browser/|Chrome]] 8 or later
  * [[http://www.apple.com/safari/|Safari]] 5.1 or later

At the moment, we do not recommend using Opera for this feature. Internet Explorer, unfortunately, does not support WebGL at all.

===== Enabling WebGL =====
If you are using a supported browser and still receive a message about not having WebGL support, you might need to enable it separately.

Depending on your browser, WebGL might not be enabled by default, or you might run into your graphics card being blacklisted. This can be overridden, generally without causing any stability issues.
