Detailed Description

uses the squarify tree map layout algorithm

vtkSquarigyLayoutStrategy partitions the space for child vertices into regions that use all avaliable space and are as close to squares as possible. The algorithm also takes into account the relative vertex size.

Thanks:
The squarified tree map algorithm comes from: Bruls, D.M., C. Huizing, J.J. van Wijk. Squarified Treemaps. In: W. de Leeuw, R. van Liere (eds.), Data Visualization 2000, Proceedings of the joint Eurographics and IEEE TCVG Symposium on Visualization, 2000, Springer, Vienna, p. 33-42.

Member Function Documentation

static vtkSquarifyLayoutStrategy* vtkSquarifyLayoutStrategy::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkSquarifyLayoutStrategy::GetClassName (  )  [virtual]

Reimplemented from vtkTreeMapLayoutStrategy.

static int vtkSquarifyLayoutStrategy::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkTreeMapLayoutStrategy.

virtual int vtkSquarifyLayoutStrategy::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkTreeMapLayoutStrategy.

static vtkSquarifyLayoutStrategy* vtkSquarifyLayoutStrategy::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkTreeMapLayoutStrategy.

void vtkSquarifyLayoutStrategy::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 vtkTreeMapLayoutStrategy.

virtual char* vtkSquarifyLayoutStrategy::GetSizeFieldName (  )  [virtual]

The field name associated with the size of the vertex.

virtual void vtkSquarifyLayoutStrategy::SetSizeFieldName ( const char *   )  [virtual]

The field name associated with the size of the vertex.

void vtkSquarifyLayoutStrategy::Layout ( vtkTree inputTree,
vtkDataArray coordsArray 
) [virtual]

Perform the layout of a tree and place the results as 4-tuples in coordsArray (Xmin, Xmax, Ymin, Ymax).

Implements vtkTreeMapLayoutStrategy.
