PolyDataAlgorithmReader
VTKExamples/Cxx/Developers/PolyDataAlgorithmReader
Description¶
This example demonstrates a reader that takes nothing as input and produces a vtkPolyData as output.
Code¶
PolyDataAlgorithmReader.cxx
#include <vtkSmartPointer.h> #include <vtkPolyData.h> #include "vtkTestReader.h" int main (int, char *[]) { vtkSmartPointer<vtkTestReader> reader = vtkSmartPointer<vtkTestReader>::New(); reader->Update(); vtkPolyData* polydata = reader->GetOutput(); polydata->Print(std::cout); return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(PolyDataAlgorithmReader) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(PolyDataAlgorithmReader MACOSX_BUNDLE PolyDataAlgorithmReader.cxx) target_link_libraries(PolyDataAlgorithmReader ${VTK_LIBRARIES})
Download and Build PolyDataAlgorithmReader¶
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 Some tarballs may be missing or out-of-date.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 PolyDataAlgorithmReader and its CMakeLists.txt file. Once the tarball PolyDataAlgorithmReader.tar has been downloaded and extracted,
cd PolyDataAlgorithmReader/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:
./PolyDataAlgorithmReader
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.
