Member Function Documentation

void ForceBundler::bundleEdges	(	int	cycles,
		int	iterations,
		double	springConstant
	)

bundleEdges performs the main bundling algorithm on the graph.

Parameters

cycles	determines how many cycles the edge bundling process iterates over.
iterations	specifies the number of iterations within one cycle.
springConstant	denotes the stiffness of the edges

DO ALL THE CYCLES!

DO ALL THE ITERATIONS!

DO ALL THE EDGES!

COMPARE ALL THE EDGES!

QVector< QVector< double > > * ForceBundler::calculateCompatibilities ( QList< Edge * > * edges )

UNUSED: Deprecated approach that also calculates pairwise compatibilities for the list of passed edges. Does not sort out smaller compatibilities.

Parameters

edges list of edges the pairwise compatibilities are to be calculated from

Returns: a vector that stores for each edge a vector containing the compatibilities to all other edges

QVector< QMap< int, double > > * ForceBundler::compatibleEdges ( QList< Edge * > * edges )

for performance reasons, the costly compatibility calculation is performed only once per bundling call and stored in a Map.

Parameters

edges list of edges the pairwise compatibilities are to be calculated from

Returns: a vector that stores for each edge a map of compatible edges with a compatibility > 0.1

void ForceBundler::setGraph ( Graph * g )

inline

sets the ForceBundler's graph to a new pointer.

Parameters

g	pointer to a new graph.

void ForceBundler::setProgress ( int p )

signal

TODO signal to notify the main window's progress bar of the progress of graph generation
