It willrotate the cone 360 degrees and then exit. The basic // setup of source -> mapper -> actor -> renderer -> renderwindow is // typical of most VTK programs. // // // First include the required header files for the vtk classes we are using // #include "vtkActor.h" #include "vtkCamera.h" #include "vtkConeSource.h" #include "vtkPolyDataMapper.h" #include "vtkRenderWindow.h" #include "vtkRenderer.h" int main() { // // Next we create an instance of vtkConeSource and set some of its // properties // vtkConeSource *cone = vtkConeSource::New(); cone->SetHeight(3.0); cone->SetRadius(1.0); cone->SetResolution(10); // // We create an instance of vtkPolyDataMapper to map the polygonal data // into graphics primitives. We connect the output of the cone souece // to the input of this mapper // vtkPolyDataMapper *coneMapper = vtkPolyDataMapper::New(); coneMapper->SetInputConnection(cone->GetOutputPort()); // // Create an actor to represent the cone. The actor coordinates rendering of // the graphics primitives for a mapper. We set this actor's mapper to be // coneMapper which we created above. // vtkActor *coneActor = vtkActor::New(); coneActor->SetMapper(coneMapper); // // Create the Renderer and assign actors to it. A renderer is like a // viewport. It is part or all of a window on the screen and it is // responsible for drawing the actors it has. We also set the background // color here // vtkRenderer *ren1= vtkRenderer::New(); ren1->AddActor(coneActor); ren1->SetBackground(0.1, 0.2, 0.4); // // Finally we create the render window which will show up on the screen // We put our renderer into the render window using AddRenderer. We also // set the size to be 300 pixels by 300 // vtkRenderWindow *renWin = vtkRenderWindow::New(); renWin->AddRenderer(ren1); renWin->SetSize(300, 300); // // Now we loop over 360 degreeees and render the cone each time // int i; for (i = 0; i < 360; ++i) { // Render the image and rotate the active camera by one degree renWin->Render(); ren1->GetActiveCamera()->Azimuth(1); } // // Free up any objects we created // cone->Delete(); coneMapper->Delete(); coneActor->Delete(); ren1->Delete(); renWin->Delete(); return 0; }
