Detailed Description

Main GLExtensions class for managing OpenGL extensions per graphics context.

Member Function Documentation

◆ Get()

static GLExtensions* osg::GLExtensions::Get	(	unsigned int	contextID,
		bool	createIfNotInitalized
	)

static

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 NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object only be created with the graphics context associated with ContextID..

◆ Set()

static void osg::GLExtensions::Set	(	unsigned int	contextID,
		GLExtensions *	extensions
	)

static

allows users to override the extensions across graphics contexts.

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.
