Firstly, thanks to the visualisation toolkit for the cone and cylinder samples. Btw, below is my first modified coding.

// First include the required header files for the VTK classes we are using.
#include "vtkConeSource.h"
#include "vtkPolyDataMapper.h"
#include "vtkRenderWindow.h"
#include "vtkCamera.h"
#include "vtkRenderer.h"
#include "vtkActor.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkProperty.h"
int main( int argc, char *argv[] )
{

// Next we create an instance of vtkConeSource and set some of its
// properties. The instance of vtkConeSource "cone" is part of a
// visualization pipeline (it is a source process object); it produces data
// (output type is vtkPolyData) which other filters may process.

vtkConeSource *cone = vtkConeSource::New();
cone->SetHeight( 3.0 );
cone->SetRadius( 1.0 );
cone->SetResolution( 10 );

// In this example we terminate the pipeline with a mapper process object.
// (Intermediate filters such as vtkShrinkPolyData could be inserted in
// between the source and the mapper.) 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->SetInput( cone->GetOutput() );

// Create an actor to represent the cone. The actor orchestrates rendering
// of the mapper's graphics primitives. An actor also refers to properties
// via a vtkProperty instance, and includes an internal transformation
// matrix. We set this actor's mapper to be coneMapper which we created
// above.

vtkActor *coneActor = vtkActor::New();
coneActor->SetMapper( coneMapper );
coneActor->GetProperty()->SetColor(1.0000, 0.3882, 0.2784);
coneActor->RotateX(30.0);
coneActor->RotateY(-45.0);

// 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();
vtkRenderWindow *renWin = vtkRenderWindow::New();
renWin->AddRenderer(ren1);
vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
iren->SetRenderWindow(renWin);
// Add the actors to the renderer, set the background and size

ren1->AddActor(coneActor);
ren1->SetBackground(0.1, 0.2, 0.4);
renWin->SetSize(200, 200);
// We'll zoom in a little by accessing the camera and invoking a "Zoom"
// method on it.

ren1->GetActiveCamera()->Zoom(1.5);
renWin->Render();

// This starts the event loop and as a side effect causes an initial render.
iren->Start();

// Exiting from here, we have to delete all the instances that
// have been created.
cone->Delete();
coneMapper->Delete();
coneActor->Delete();
ren1->Delete();
renWin->Delete();
iren->Delete();

return 0;
