#include <vtkFast2DLayoutStrategy.h>
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.

static vtkFast2DLayoutStrategy* vtkFast2DLayoutStrategy::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject.
virtual const char* vtkFast2DLayoutStrategy::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkGraphLayoutStrategy.
static int vtkFast2DLayoutStrategy::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type 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.
Reimplemented from vtkGraphLayoutStrategy.
virtual int vtkFast2DLayoutStrategy::IsA | ( | const char * | name | ) | [virtual] |

void vtkFast2DLayoutStrategy::PrintSelf | ( | ostream & | os, | |
vtkIndent | indent | |||
) | [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 vtkGraphLayoutStrategy.
virtual void vtkFast2DLayoutStrategy::SetRandomSeed | ( | int | ) | [virtual] |
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 int vtkFast2DLayoutStrategy::GetRandomSeed | ( | ) | [virtual] |
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 int vtkFast2DLayoutStrategy::GetMaxNumberOfIterations | ( | ) | [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 int vtkFast2DLayoutStrategy::GetIterationsPerLayout | ( | ) | [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 void vtkFast2DLayoutStrategy::SetInitialTemperature | ( | float | ) | [virtual] |
Set the initial temperature. The temperature default is '5' for no particular reason Note: The strong recommendation is that you do not change this parameter. :)
virtual float vtkFast2DLayoutStrategy::GetInitialTemperature | ( | ) | [virtual] |
Set the initial temperature. The temperature default is '5' for no particular reason Note: The strong recommendation is that you do not change this parameter. :)
virtual void vtkFast2DLayoutStrategy::SetCoolDownRate | ( | double | ) | [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. :)
virtual double vtkFast2DLayoutStrategy::GetCoolDownRate | ( | ) | [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. :)
virtual void vtkFast2DLayoutStrategy::SetRestDistance | ( | float | ) | [virtual] |
Manually set the resting distance. Otherwise the distance is computed automatically.
virtual float vtkFast2DLayoutStrategy::GetRestDistance | ( | ) | [virtual] |
Manually set the resting distance. Otherwise the distance is computed automatically.
virtual void vtkFast2DLayoutStrategy::Initialize | ( | ) | [virtual] |
This strategy sets up some data structures for faster processing of each Layout() call
Reimplemented from vtkGraphLayoutStrategy.
virtual void vtkFast2DLayoutStrategy::Layout | ( | ) | [virtual] |
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.
virtual int vtkFast2DLayoutStrategy::IsLayoutComplete | ( | ) | [inline, virtual] |
I'm an iterative layout so this method lets the caller know if I'm done laying out the graph
