WriteVTP
VTKExamples/Cxx/IO/WriteVTP
Description¶
In this example, we add 10 points to a polygonal data (polydata) object and write the result to a VTP file.
Code¶
WriteVTP.cxx
#include <vtkVersion.h> #include <vtkCellArray.h> #include <vtkPoints.h> #include <vtkXMLPolyDataWriter.h> #include <vtkPolyData.h> #include <vtkSmartPointer.h> int main ( int, char *[] ) { // Create 10 points. vtkSmartPointer<vtkPoints> points = vtkSmartPointer<vtkPoints>::New(); for ( unsigned int i = 0; i < 10; ++i ) { points->InsertNextPoint ( i, i, i ); } // Create a polydata object and add the points to it. vtkSmartPointer<vtkPolyData> polydata = vtkSmartPointer<vtkPolyData>::New(); polydata->SetPoints(points); // Write the file vtkSmartPointer<vtkXMLPolyDataWriter> writer = vtkSmartPointer<vtkXMLPolyDataWriter>::New(); writer->SetFileName("test.vtp"); #if VTK_MAJOR_VERSION <= 5 writer->SetInput(polydata); #else writer->SetInputData(polydata); #endif // Optional - set the mode. The default is binary. //writer->SetDataModeToBinary(); //writer->SetDataModeToAscii(); writer->Write(); return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(WriteVTP) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(WriteVTP MACOSX_BUNDLE WriteVTP.cxx) target_link_libraries(WriteVTP ${VTK_LIBRARIES})
Download and Build WriteVTP¶
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 Some tarballs may be missing or out-of-date.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 WriteVTP and its CMakeLists.txt file. Once the tarball WriteVTP.tar has been downloaded and extracted,
cd WriteVTP/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:
./WriteVTP
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.
