Detailed Description

uses the squarify tree map layout algorithm

vtkSquarifyLayoutStrategy partitions the space for child vertices into regions that use all available 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 vtkTypeMacro 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 vtkTypeMacro 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.

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

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

Implements vtkAreaLayoutStrategy.
