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.
