Detailed Description

Layout graph edges on a globe as arcs.

vtkGeoEdgeStrategy produces arcs for each edge in the input graph. This is useful for viewing lines on a sphere (e.g. the earth). The arcs may "jump" above the sphere's surface using ExplodeFactor.

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 vtkEdgeLayoutStrategy.

◆ NewInstance()

◆ PrintSelf()

void vtkGeoEdgeStrategy::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 vtkEdgeLayoutStrategy.

◆ SetGlobeRadius()

virtual void vtkGeoEdgeStrategy::SetGlobeRadius ( double  )
virtual

The base radius used to determine the earth's surface.

Default is the earth's radius in meters. TODO: Change this to take in a vtkGeoTerrain to get altitude.

◆ GetGlobeRadius()

virtual double vtkGeoEdgeStrategy::GetGlobeRadius ( )
virtual

The base radius used to determine the earth's surface.

Default is the earth's radius in meters. TODO: Change this to take in a vtkGeoTerrain to get altitude.

◆ SetExplodeFactor()

virtual void vtkGeoEdgeStrategy::SetExplodeFactor ( double  )
virtual

Factor on which to "explode" the arcs away from the surface.

A value of 0.0 keeps the values on the surface. Values larger than 0.0 push the arcs away from the surface by a distance proportional to the distance between the points. The default is 0.2.

◆ GetExplodeFactor()

virtual double vtkGeoEdgeStrategy::GetExplodeFactor ( )
virtual

Factor on which to "explode" the arcs away from the surface.

A value of 0.0 keeps the values on the surface. Values larger than 0.0 push the arcs away from the surface by a distance proportional to the distance between the points. The default is 0.2.

◆ SetNumberOfSubdivisions()

virtual void vtkGeoEdgeStrategy::SetNumberOfSubdivisions ( int  )
virtual

The number of subdivisions in the arc.

The default is 20.

◆ GetNumberOfSubdivisions()

virtual int vtkGeoEdgeStrategy::GetNumberOfSubdivisions ( )
virtual

The number of subdivisions in the arc.

The default is 20.

◆ Layout()

void vtkGeoEdgeStrategy::Layout ( )
overridevirtual

Perform the layout.

Implements vtkEdgeLayoutStrategy.
