Detailed Description

Produces a layout for a graph labeled with K-Core information.

vtkKCoreLayout creates coordinates for each vertex that can be used to perform a layout for a k-core view. Prerequisite: Vertices must have an attribute array containing their k-core number. This layout is based on the algorithm described in the paper: "k-core decomposition: a tool for the visualization of large scale networks", by Ignacio Alvarez-Hamelin et. al.

This graph algorithm appends either polar coordinates or cartesian coordinates as vertex attributes to the graph giving the position of the vertex in a layout. Input graphs must have the k-core number assigned to each vertex (default attribute array storing kcore numbers is "kcore").

Epsilon - this factor is used to adjust the amount vertices are 'pulled' out of their default ring radius based on the number of neighbors in higher cores. Default=0.2 UnitRadius - Tweaks the base unit radius value. Default=1.0

Still TODO: Still need to work on the connected-components within each shell and associated layout issues with that.

Input port 0: graph

virtual

Epsilon value used in the algorithm.

Default = 0.2

◆ GetEpsilon()

virtual float vtkKCoreLayout::GetEpsilon ( )
virtual

◆ SetUnitRadius()

virtual void vtkKCoreLayout::SetUnitRadius ( float  )
virtual

Unit Radius value used in the algorithm.

Default = 1.0

◆ GetUnitRadius()

virtual float vtkKCoreLayout::GetUnitRadius ( )
virtual

◆ RequestData()

int vtkKCoreLayout::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overridevirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkGraphAlgorithm.
