a simple fast 2D graph layout
This class is a density grid based force directed layout strategy. Also please note that 'fast' is relative to quite slow. :) The layout running time is O(V+E) with an extremely high constant.

virtual void vtkFast2DLayoutStrategy::SetRandomSeed |
( |

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

virtual void vtkFast2DLayoutStrategy::SetMaxNumberOfIterations |
( |
int |
| ) |
|
|
virtual |
Set/Get the maximum number of iterations to be used. The higher this number, the more iterations through the algorithm is possible, and thus, the more the graph gets modified. The default is '100' for no particular reason Note: The strong recommendation is that you do not change this parameter. :)

virtual void vtkFast2DLayoutStrategy::SetIterationsPerLayout |
( |
int |
| ) |
|
|
virtual |
Set/Get the number of iterations per layout. The only use for this ivar is for the application to do visualizations of the layout before it's complete. The default is '100' to match the default 'MaxNumberOfIterations' Note: Changing this parameter is just fine :)

virtual |
Set/Get the Cool-down rate. The higher this number is, the longer it will take to "cool-down", and thus, the more the graph will be modified. The default is '10' for no particular reason. Note: The strong recommendation is that you do not change this parameter. :)

This is the layout method where the graph that was set in SetGraph() is laid out. The method can either entirely layout the graph or iteratively lay out the graph. If you have an iterative layout please implement the IsLayoutComplete() method.
Implements vtkGraphLayoutStrategy.
