const [virtual]

apply the OpenGL state attributes.

The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from osg::StateAttribute.

static Extensions* osg::ClampColor::getExtensions	(	unsigned int	contextID,
		bool	createIfNotInitalized
	)			[static]

Returns the Extensions object for the given context.

If createIfNotInitalized is true and the Exentsions object doesn't exist, getExtensions() creates it on the given context. Returns NULL if createIfNotInitalized is false and the Extensions object doesn't exist.

static void osg::ClampColor::setExtensions	(	unsigned int	contextID,
		Extensions *	extensions
	)			[static]

setExtensions() 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.
