• 1, Open Qt Creator. In the file menu select new project and create a Qt widget Application.

  • 2, Open pro file and VTK include path, add used libs.

      INCLUDEPATH += ./work/include/vtk-8.2
  ...

  LIBS += -L/usr/local/lib/  -lvtkChartsCore-8.2.1

  LIBS += -L/usr/local/lib/  -lvtkCommonColor-8.2.1

  LIBS += -L/usr/local/lib/  -lvtkCommonComputationalGeometry-8.2.1

  LIBS += -L/usr/local/lib/  -lvtkCommonCore-8.2.1
  ...

  • 3, setQSurfaceFormat

      #include "mainwindow.h"

  #include <QApplication>

  #include <vtkQImageToImageSource.h>
  #include <vtkSmartPointer.h>
  #include <QLabel>
  #include <QVTKOpenGLNativeWidget.h>
  int main(int argc, char *argv[])
  {
      QSurfaceFormat::setDefaultFormat(QVTKOpenGLNativeWidget::defaultFormat());
      QApplication a(argc, argv);
      MainWindow w;
      w.show();
      return a.exec();
  }

  • 4, Create a QVTKOpenGLWidget

      //step 0: set it to a window:   auto vw = new  QVTKOpenGLWidget(this) ;   vtkRenderWindow *renWin = vw->GetRenderWindow();   ui->tabWidget->addTab( vw, __FUNCTION__);

    vtkRenderer *render= vtkRenderer::New();

    render->SetBackground( 0.1, 0.2, 0.4 );

    vtkSmartPointer coneSource = vtkSmartPointer::New(); coneSource->SetRadius(.2); coneSource->SetHeight(.5); coneSource->SetCenter(0, 0, 0);

      vtkSmartPointer<vtkPolyDataMapper> coneMapper =
      vtkSmartPointer<vtkPolyDataMapper>::New();
  coneMapper->SetInputConnection(coneSource->GetOutputPort());
  vtkSmartPointer<vtkActor> coneActor =
      vtkSmartPointer<vtkActor>::New();
  coneActor->SetMapper(coneMapper);

  vtkSmartPointer<vtkActor> oriConeActor =
      vtkSmartPointer<vtkActor>::New();
  oriConeActor->SetMapper(coneMapper);

    render->AddActor(oriConeActor); renWin->AddRenderer( render );
