Detailed Description

Interface for a class that can create a Node from a set of features and a style definition. You will provide this to a FeatureModeGraph when creating a feature node in a driver.

Member Function Documentation

virtual bool osgEarth::Features::FeatureNodeFactory::createOrUpdateNode	(	FeatureCursor *	cursor,
		const Style &	style,
		const FilterContext &	context,
		osg::ref_ptr< osg::Node > &	node
	)		[pure virtual]

Render (or update) a list of features into a node according to the specified style.

Implemented in anonymous_namespace{FeatureLabelModelSource.cpp}::LabelNodeFactory, anonymous_namespace{FeatureStencilModelSource.cpp}::StencilVolumeNodeFactory, and osgEarth::Features::GeomFeatureNodeFactory.

virtual osg::Group* osgEarth::Features::FeatureNodeFactory::getOrCreateStyleGroup	(	const Style &	style,
		Session *	session
	)		[inline, virtual]

Creates a group that will contain all the geometry corresponding to a given style. The subclass has the option of overriding this in order to create a custom implementation.

Reimplemented in anonymous_namespace{FeatureStencilModelSource.cpp}::StencilVolumeNodeFactory.
