Currently broken: Can you glyph something besides a vertex at each point? What are "icons"?

#include <vtkSmartPointer.h>
#include <vtkMutableUndirectedGraph.h>
#include <vtkGraphWriter.h>
#include <vtkGraphLayoutView.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkGraphLayoutStrategy.h>
#include <vtkSimple2DLayoutStrategy.h>

int main(int, char *[])
{
  vtkSmartPointer<vtkMutableUndirectedGraph> g =
    vtkSmartPointer<vtkMutableUndirectedGraph>::New();

  vtkIdType v1 = g->AddVertex();
  vtkIdType v2 = g->AddVertex();

  g->AddEdge(v1, v2);
  g->AddEdge(v1, v2);

  vtkSmartPointer<vtkGraphLayoutView> graphLayoutView =
    vtkSmartPointer<vtkGraphLayoutView>::New();
  graphLayoutView->AddRepresentationFromInput(g);
  graphLayoutView->ResetCamera();
  graphLayoutView->Render();
  graphLayoutView->IconVisibilityOn();
  graphLayoutView->GetInteractor()->Start();

  return EXIT_SUCCESS;
}

Download and Build NodeShape

Click here to download NodeShape. and its CMakeLists.txt file.

Once the tarball NodeShape.tar has been downloaded and extracted,

cd NodeShape/build 

• If VTK is installed:

cmake ..

• If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:

cmake -DVTK_DIR:PATH=/home/me/vtk_build ..

Build the project:

make

and run it:

./NodeShape

WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
