#include <vtkKCoreLayout.h>
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.

| static vtkKCoreLayout* vtkKCoreLayout::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkGraphAlgorithm.
| static int vtkKCoreLayout::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkGraphAlgorithm.
| virtual int vtkKCoreLayout::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

| void vtkKCoreLayout::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkGraphAlgorithm.
Convenience function provided for setting the graph input.
| int vtkKCoreLayout::FillInputPortInformation | ( | int | port, |
| vtkInformation * | info | ||
| ) | [virtual] |
Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.
Reimplemented from vtkGraphAlgorithm.
