Detailed Description

randomly places vertices in 2 or 3 dimensions

Assigns points to the vertices of a graph randomly within a bounded range.

.SECION Thanks Thanks to Brian Wylie from Sandia National Laboratories for adding incremental layout capabilities.

virtual void vtkRandomLayoutStrategy::SetRandomSeed ( int  )

virtual

Seed the random number generator used to compute point positions. This has a significant effect on their final positions when the layout is complete.

Set / get the region in space in which to place the final graph. The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual void vtkRandomLayoutStrategy::SetGraphBounds ( double  [6] )

virtual

Set / get the region in space in which to place the final graph. The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual

Set / get the region in space in which to place the final graph. The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual void vtkRandomLayoutStrategy::SetAutomaticBoundsComputation ( int  )

virtual

Turn on/off automatic graph bounds calculation. If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual int vtkRandomLayoutStrategy::GetAutomaticBoundsComputation ( )

virtual

Turn on/off automatic graph bounds calculation. If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual void vtkRandomLayoutStrategy::AutomaticBoundsComputationOn ( )

virtual

Turn on/off automatic graph bounds calculation. If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual

Turn on/off automatic graph bounds calculation. If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual void vtkRandomLayoutStrategy::SetThreeDimensionalLayout ( int  )

virtual

Turn on/off layout of graph in three dimensions. If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

virtual int vtkRandomLayoutStrategy::GetThreeDimensionalLayout ( )

virtual

Turn on/off layout of graph in three dimensions. If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

virtual void vtkRandomLayoutStrategy::ThreeDimensionalLayoutOn ( )

virtual

Turn on/off layout of graph in three dimensions. If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

Turn on/off layout of graph in three dimensions. If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

void vtkRandomLayoutStrategy::SetGraph ( vtkGraph *  graph )

virtual

Set the graph to layout.

Reimplemented from vtkGraphLayoutStrategy.

void vtkRandomLayoutStrategy::Layout ( )

virtual

Perform the random layout.
