GraphAlgorithmSource

VTKExamples/Cxx/Developers/GraphAlgorithmSource

Description

This example produces a vtkGraph as output.

Code

GraphAlgorithmSource.cxx

#include <vtkSmartPointer.h>
#include <vtkGraph.h>
#include <vtkMutableUndirectedGraph.h>

#include "vtkTestGraphAlgorithmSource.h"

int main (int, char *[])
{
  vtkSmartPointer<vtkTestGraphAlgorithmSource> source =
    vtkSmartPointer<vtkTestGraphAlgorithmSource>::New();
  source->Update();

  vtkGraph* outputGraph = source->GetOutput();

  std::cout << "Output number of vertices: "
            << outputGraph->GetNumberOfVertices() << std::endl;

  return EXIT_SUCCESS;
}

Download and Build GraphAlgorithmSource

Click here to download GraphAlgorithmSource and its CMakeLists.txt file. Once the tarball GraphAlgorithmSource.tar has been downloaded and extracted,

cd GraphAlgorithmSource/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:

./GraphAlgorithmSource

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.
