AlgorithmSource
VTKExamples/Cxx/Developers/AlgorithmSource
Description¶
This example demonstrates how to create a source that returns a custom class. To test that it is working, the class vtkTest1 simply stores a double named 'Value' that is instantiated to the value of 4.5. Example.cxx instantiates a vtkTestSource which produces a vtkTest1.
Code¶
AlgorithmSource.cxx
#include <vtkSmartPointer.h> #include "vtkTestAlgorithmSource.h" #include "vtkTest1.h" int main(int, char *[]) { vtkTestAlgorithmSource* source = vtkTestAlgorithmSource::New(); source->Update(); vtkTest1* test = source->GetOutput(); std::cout << test->GetValue() << std::endl; return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(AlgorithmSource) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(AlgorithmSource MACOSX_BUNDLE AlgorithmSource.cxx) target_link_libraries(AlgorithmSource ${VTK_LIBRARIES})
Download and Build AlgorithmSource¶
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 Some tarballs may be missing or out-of-date.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 AlgorithmSource and its CMakeLists.txt file. Once the tarball AlgorithmSource.tar has been downloaded and extracted,
cd AlgorithmSource/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:
./AlgorithmSource
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.
