Produce filled convex hulls around subsets of vertices in a vtkGraph.
Produces a vtkPolyData comprised of filled polygons of the convex hull of a cluster. Alternatively, you may choose to output bounding rectangles. Clusters with fewer than three vertices are artificially expanded to ensure visibility (see vtkConvexHull2D).
The first input is a vtkGraph with points, possibly set by passing the graph through vtkGraphLayout (z-values are ignored). The second input is a vtkAnnotationsLayer containing vtkSelectionNodeS of vertex ids (the 'clusters' output of vtkTulipReader for example).
Setting OutlineOn() additionally produces outlines of the clusters on output port 1.
Three arrays are added to the cells of the output: "Hull id"; "Hull name"; and "Hull color".
Note: This filter operates in the x,y-plane and as such works best with an interactor style that does not allow camera rotation, such as vtkInteractorStyleRubberBand2D.

Set the shape of the hulls to bounding rectangle.
void vtkGraphAnnotationLayersFilter::SetHullShapeToConvexHull | ( | ) |
Set the shape of the hulls to convex hull. Default.
void vtkGraphAnnotationLayersFilter::SetMinHullSizeInWorld | ( | double | size | ) |
Set the minimum x,y-dimensions of each hull in world coordinates. Defaults to 1.0. Set to 0.0 to disable.
void vtkGraphAnnotationLayersFilter::SetMinHullSizeInDisplay | ( | int | size | ) |
Set the minimum x,y-dimensions of each hull in pixels. You must also set a vtkRenderer. Defaults to 1. Set to 0 to disable.
void vtkGraphAnnotationLayersFilter::SetRenderer | ( | vtkRenderer * | renderer | ) |
Renderer needed for MinHullSizeInDisplay calculation. Not reference counted.
