Detailed Description

hierarchical orbital layout

Assigns points to the nodes of a tree to an orbital layout. Each parent is orbited by its children, recursively.

Thanks:
Thanks to the galaxy for inspiring this layout strategy.

Return 1 if this class 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.

◆ PrintSelf()

void vtkTreeOrbitLayoutStrategy::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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.

◆ Layout()

void vtkTreeOrbitLayoutStrategy::Layout ( )
overridevirtual

Perform the orbital layout.

Implements vtkGraphLayoutStrategy.

◆ SetLogSpacingValue()

virtual void vtkTreeOrbitLayoutStrategy::SetLogSpacingValue ( double  )
virtual

The spacing of orbital levels.

Levels near zero give more space to levels near the root, while levels near one (the default) create evenly-spaced levels. Levels above one give more space to levels near the leaves.

◆ GetLogSpacingValue()

virtual double vtkTreeOrbitLayoutStrategy::GetLogSpacingValue ( )
virtual

◆ SetLeafSpacing()

virtual void vtkTreeOrbitLayoutStrategy::SetLeafSpacing ( double  )
virtual

The spacing of leaves.

Levels near one evenly space leaves with no gaps between subtrees. Levels near zero creates large gaps between subtrees.

◆ GetLeafSpacing()

virtual double vtkTreeOrbitLayoutStrategy::GetLeafSpacing ( )
virtual

◆ SetChildRadiusFactor()

virtual void vtkTreeOrbitLayoutStrategy::SetChildRadiusFactor ( double  )
virtual

This is a magic number right now.

Controls the radius of the child layout, all of this should be fixed at some point with a more logical layout. Defaults to .5 :)
