ProgressReport
VTKExamples/Cxx/Developers/ProgressReport
Description¶
This example demonstrates how to get the progress of a filter. This requires that the filter is updating its progress in a sensible way. A sample filter is provided which loops through the input points and updates its progress along the way.
Code¶
ProgressReport.cxx
#include <vtkSmartPointer.h> #include <vtkPoints.h> #include <vtkPolyData.h> #include <vtkSphereSource.h> #include <vtkCallbackCommand.h> #include <vtkCommand.h> #include "vtkTestProgressReportFilter.h" void ProgressFunction(vtkObject* caller, long unsigned int eventId, void* clientData, void* callData); int main(int, char *[]) { vtkSmartPointer<vtkSphereSource> sphereSource = vtkSmartPointer<vtkSphereSource>::New(); sphereSource->Update(); vtkSmartPointer<vtkCallbackCommand> progressCallback = vtkSmartPointer<vtkCallbackCommand>::New(); progressCallback->SetCallback(ProgressFunction); vtkSmartPointer<vtkTestProgressReportFilter> testFilter = vtkSmartPointer<vtkTestProgressReportFilter>::New(); testFilter->SetInputConnection(sphereSource->GetOutputPort()); testFilter->AddObserver(vtkCommand::ProgressEvent, progressCallback); testFilter->Update(); return EXIT_SUCCESS; } void ProgressFunction ( vtkObject* caller, long unsigned int vtkNotUsed(eventId), void* vtkNotUsed(clientData), void* vtkNotUsed(callData) ) { vtkTestProgressReportFilter* testFilter = static_cast<vtkTestProgressReportFilter*>(caller); std::cout << "Progress: " << testFilter->GetProgress() << std::endl; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(ProgressReport) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(ProgressReport MACOSX_BUNDLE ProgressReport.cxx) target_link_libraries(ProgressReport ${VTK_LIBRARIES})
Download and Build ProgressReport¶
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 Some tarballs may be missing or out-of-date.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 ProgressReport and its CMakeLists.txt file. Once the tarball ProgressReport.tar has been downloaded and extracted,
cd ProgressReport/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:
./ProgressReport
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.
