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;
}

Download and Build AlgorithmSource
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.
