.SECTION Thanks Thanks to Brian Wylie for adding functionality for allowing this layout to be incremental.
To create an instance of class vtkForceDirectedLayoutStrategy, simply invoke its constructor as follows
obj = vtkForceDirectedLayoutStrategy
obj
is an instance of the vtkForceDirectedLayoutStrategy class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkForceDirectedLayoutStrategy = obj.NewInstance ()
vtkForceDirectedLayoutStrategy = obj.SafeDownCast (vtkObject o)
obj.SetRandomSeed (int )

the layout is complete.
int = obj.GetRandomSeedMaxValue ()

the layout is complete.

the layout is complete.
obj.SetGraphBounds (double , double , double , double , double , double )

boolean is off, then the manually specified GraphBounds is used.

boolean is off, then the manually specified GraphBounds is used.

boolean is off, then the manually specified GraphBounds is used.
If on, then the input's bounds us used as the graph bounds.
obj.SetMaxNumberOfIterations (int )
- 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 '50' for no particular reason
int = obj.GetMaxNumberOfIterationsMinValue ()
- 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 '50' for no particular reason
int = obj.GetMaxNumberOfIterationsMaxValue ()
- 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 '50' for no particular reason
int = obj.GetMaxNumberOfIterations ()
- 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 '50' for no particular reason
obj.SetIterationsPerLayout (int )
- 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 '50' to match the default 'MaxNumberOfIterations'
int = obj.GetIterationsPerLayoutMinValue ()
- 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 '50' to match the default 'MaxNumberOfIterations'
int = obj.GetIterationsPerLayoutMaxValue ()
- 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 '50' to match the default 'MaxNumberOfIterations'
int = obj.GetIterationsPerLayout ()
- 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 '50' to match the default 'MaxNumberOfIterations'
obj.SetCoolDownRate (double )
- 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.
double = obj.GetCoolDownRateMinValue ()
- 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.
double = obj.GetCoolDownRateMaxValue ()
- 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.
double = obj.GetCoolDownRate ()
- 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.
obj.SetThreeDimensionalLayout (int )
- Turn on/off layout of graph in three dimensions. If off, graph
layout occurs in two dimensions. By default, three dimensional
layout is off.
int = obj.GetThreeDimensionalLayout ()

layout occurs in two dimensions. By default, three dimensional

obj.Initialize ()
- This strategy sets up some data structures
for faster processing of each Layout() call
obj.Layout ()
- 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.
int = obj.IsLayoutComplete ()
