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; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(GraphAlgorithmSource) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(GraphAlgorithmSource MACOSX_BUNDLE GraphAlgorithmSource.cxx) target_link_libraries(GraphAlgorithmSource ${VTK_LIBRARIES})
Download and Build GraphAlgorithmSource¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
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.
