Detailed Description

places vertices on circles in 3D

Places vertices on circles depending on the graph vertices hierarchy level. The source graph could be vtkDirectedAcyclicGraph or vtkDirectedGraph if MarkedStartPoints array was added. The algorithm collects the standalone points, too and take them to a separated circle. If method is FixedRadiusMethod, the radius of the circles will be equal. If method is FixedDistanceMethod, the distance beetwen the points on circles will be equal.

In first step initial points are searched. A point is initial, if its in degree equal zero and out degree is greater than zero (or marked by MarkedStartVertices and out degree is greater than zero). Independent vertices (in and out degree equal zero) are collected separatelly. In second step the hierarchical level is generated for every vertex. In third step the hierarchical order is generated. If a vertex has no hierarchical level and it is not independent, the graph has loop so the algorithm exit with error message. Finally the vertices positions are calculated by the hierarchical order and by the vertices hierarchy levels.

Member Function Documentation

static vtkSimple3DCirclesStrategy* vtkSimple3DCirclesStrategy::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkSimple3DCirclesStrategy::GetClassName ( ) [virtual]

Reimplemented from vtkGraphLayoutStrategy.

static int vtkSimple3DCirclesStrategy::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 vtkSimple3DCirclesStrategy::IsA ( const char * name ) [virtual]

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.

static vtkSimple3DCirclesStrategy* vtkSimple3DCirclesStrategy::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkGraphLayoutStrategy.

void vtkSimple3DCirclesStrategy::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.
