Detailed Description

a real graph (sub-)set "set" refers to the fact that this can be any subset of nodes of a graph.

shows nodes (currently VisKeywords) connected by edges.

The layout is done by a physical force simulation: all nodes repell each other like electrically charged particels. all edges pull nodes together like a spring would do.

as spring forces are lineary but repellent forces are quadratic, there is a well defined local energy minimum approached by the whole graph. however it can take a long time to reach this equilibrium.

Constructor & Destructor Documentation

org.hfbk.vis.visnode.VisSet.VisSet	(	Node	set,
		Vector3f	pos
	)

build a VisSet. it gatheres all subnodes (the graph) by itself so all this nodes are excluded from the global recursion (

See also:

org.hfbk.vis.VisRoot.recurseNodes) by deletion herein.

Parameters:

	set	the set root node which references all nodes
	pos

by default, we just render VisKeywords for each Node, appending the type as (type) to the keyword label.
