* @class vtkTreeMapLayoutStrategy
|
||
|
|
* @brief abstract superclass for all tree map layout strategies
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* All subclasses of this class perform a tree map layout on a tree.
|
||
|
|
* This involves assigning a rectangular region to each vertex in the tree,
|
||
|
|
* and placing that information in a data array with four components per
|
||
|
|
* tuple representing (Xmin, Xmax, Ymin, Ymax).
|
||
|
|
*
|
||
|
|
* Instances of subclasses of this class may be assigned as the layout
|
||
|
|
* strategy to vtkTreeMapLayout
|
||
|
|
*
|
||
|
|
* @par Thanks:
|
||
|
|
* Thanks to Brian Wylie and Ken Moreland from Sandia National Laboratories
|
||
|
|
* for help developing this class.
