makVrv::DtOceanExtractorVisitor Class Reference

DtOceanExtractorVisitor tags nodes as static ocean via the setUserValue capability, based on a texture name or texture regular expression. Terrain nodes have a DtOsgTextureKeyHolder in their userData fields which holds a list of the keys to a texture map of all the textures applied to the node. If one of the textures on the node matches the search string or regular expression than the node has a setUserValue( "isStaticOcean", true ) set on it.

Constructor & Destructor Documentation

makVrv::DtOceanExtractorVisitor::DtOceanExtractorVisitor	(	DtTextureVisitor::TextureMap &	textureMap,
		const std::string &	rule,
		bool	isRegEx,
		bool	indirect
	)

Default CTOR Inputs are the map of textures held be the terrain pactch, the search string or regular expression, and a flag saying if the rule is a regular expression or not.

Virtual DTOR.

Member Function Documentation

virtual void makVrv::DtOceanExtractorVisitor::apply ( osg::Group &  group )

virtual

This is the method called when the visitor is visiting groups We detect the DtTerrainPatchGroup (via dynamic cast) as the top-most group, allowing the visitor to do initialization and cleanup. Cleanup includes removing any texture names from the texture map that are 'extracted'.

virtual void makVrv::DtOceanExtractorVisitor::apply ( osg::Node &  node )

virtual

This is the method called when the visitor visits any non-group node.

virtual bool makVrv::DtOceanExtractorVisitor::nodesExtracted ( ) const

virtual

Return whether any nodes were marked as static ocean.

virtual bool makVrv::DtOceanExtractorVisitor::extractStaticOcean ( osg::Node &  node )

protectedvirtual

Method called on a node to attempt extraction.

virtual bool makVrv::DtOceanExtractorVisitor::checkTextures ( const osg::Node &  node )

protectedvirtual

Check the textures pointed to by a node against the search criteria.

virtual bool makVrv::DtOceanExtractorVisitor::makeNodeStaticOcean ( osg::Node &  node )

protectedvirtual

When a static ocean node is discovered, mark it.
