Static Methods:

.Get(unsigned in_contextID, bool createIfNotInitalized)¶

Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created then and the createIfNotInitalized flag been set to false then returns nil. If createIfNotInitalized is true then the Extensions object is automatically created. However, in this case the extension object only be created with the osg.GraphicsContext associated with ContextID.

Parameters:	in_contextID (unsigned) – createIfNotInitalized (bool) –
Return type:	osg.GLExtensions

.Set(unsigned in_contextID, osg.GLExtensions extensions)¶

Allows users to override the extensions across osg.GraphicsContext s. Typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.

Parameters:	in_contextID (unsigned) – extensions (osg.GLExtensions) –
