makVrv::DtDynamicTerrainSequenceNode Class Reference

DtDynamicTerrainSequenceNode replaces an osg::Sequence in a terrain patch (or page) that is tagged with a WRM ' animation' comment if that patch/page is parsed by the dynamic terrain parser. It supports multiple references to itself by extending DtMultiReferencedNodeContainer, with DtSequenceInstanceState as its template parameter. During a traversal of this node, a node path hash is requested and used to look up the state of the sequence for that particular reference. The osg::Sequence has its state set according to the current reference; it is 'accept'ed; and then any changed state is retrieved and stored for the next time this reference is visited.

CTOR.

makVrv::DtDynamicTerrainSequenceNode::DtDynamicTerrainSequenceNode	(	const DtDynamicTerrainSequenceNode &	sequence,
		const osg::CopyOp &	copyop = osg::CopyOp::SHALLOW_COPY
	)

Copy CTOR param[in] sequence the DtDynamicTerrainSequenceNode to copy param[in] copyop what type of copy should be used for the underlying osg::Sequence (ignored for members of this derived class). Defaults to SHALLOW_COPY.

makVrv::DtDynamicTerrainSequenceNode::DtDynamicTerrainSequenceNode	(	const osg::Sequence &	sequence,
		const osg::CopyOp &	copyop = osg::CopyOp::SHALLOW_COPY
	)

Construct from an osg::Sequence param[in] sequence the osg::Sequence to copy from param[in] copyop the type of copy to use; defaults to SHALLOW_COPY.

Member Function Documentation

virtual void makVrv::DtDynamicTerrainSequenceNode::reset ( DynamicTerrain::NodePathHash  hashIndex )

virtual

Set the state of the sequence to START and reset all internal state accordingly param[in] hashIndex the node path hash for the reference to reset.

virtual void makVrv::DtDynamicTerrainSequenceNode::traverse ( osg::NodeVisitor &  nv )

protectedvirtual

Traverse this node. The path that the node visitor used to traverse to this node is used the calculate a node path hash, which in turn is used to find the state of the reference to this node, which is set for all internal osg::Sequence variables. The sequence is then 'accept'ed. Any changed state is then retrieved and store for the next visit to this reference param[in] nv the node visitor performing the traversal.

virtual void makVrv::DtDynamicTerrainSequenceNode::collectState ( DynamicTerrain::NodePathHash  hashIndex )

protectedvirtual

Collect the animation state information from the underlying osg::sequence and store it. param[in] hashIndex the node path hash for the reference to associate the collected state with.

virtual void makVrv::DtDynamicTerrainSequenceNode::instantiateState ( DynamicTerrain::NodePathHash  hashIndex )

protectedvirtual

Look up the state for a sequence reference and set the osg::Sequence internal variables to that state param[in] hashIndex the node path hash for the reference to instantiate.
