[vtkusers] How to enable capping for Cone ?

[Girish Lande]

Hi Experts,

I am trying to draw Cone with its base closed.
For that I am calling CappingOn() function provided for same.
But it doesn't seem to work. I can't think of what can be missing here.

Following is my code.


#include "stdafx.h"

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2)
VTK_MODULE_INIT(vtkRenderingFreeType);

#include <vtkConeSource.h>
#include <vtkPolyData.h>
#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkInteractorStyleTrackballCamera.h>
#include <vtkProperty.h>

int main(int, char *[])
{
//Create a cone
vtkSmartPointer<vtkConeSource> coneSource =
vtkSmartPointer<vtkConeSource>::New();
coneSource->SetResolution(100);
coneSource->SetCapping(true);
coneSource->Update();

//Create a mapper and actor
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(coneSource->GetOutputPort());

vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
actor->GetProperty()->SetOpacity(0.5);

//Create a renderer, render window, and interactor
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);

//Add the actors to the scene
renderer->AddActor(actor);

vtkSmartPointer<vtkInteractorStyleTrackballCamera> style =
vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
renderWindowInteractor->SetInteractorStyle(style);


//Render and interact
renderWindow->SetSize(800, 800);
renderWindow->Render();
renderWindowInteractor->Start();

return EXIT_SUCCESS;
}
