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.

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 vtkSquarifyLayoutStrategy::PrintSelf	(	ostream &	os,

	)

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 vtkAreaLayoutStrategy.

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.
