vtk學習四-一個簡單的程式

#include <vtkCylinderSource.h>

#include <vtkPolyDataMapper.h>

#include <vtkRenderWindow.h>

#include <vtkRenderer.h>

#include <vtkCamera.h>

#include <vtkRenderWindowInteractor.h>

#include <vtkActor.h>

#include <vtkProperty.h>

int main()

{

 vtkCylinderSource* cone=vtkCylinderSource::New();

 cone->SetResolution(8);

 vtkPolyDataMapper* mapper=vtkPolyDataMapper::New();

 mapper->SetInput(cone->GetOutput());

 vtkActor* actor=vtkActor::New();

 actor->SetMapper(mapper);

 actor->GetProperty()->SetColor(1.000,0.228,0.3111);

 actor->RotateX(30);

 actor->RotateY(-45);

 vtkRenderer* render=vtkRenderer::New();

 vtkRenderWindow* window=vtkRenderWindow::New();

 window->AddRenderer(render);

 vtkRenderWindowInteractor* interactor=vtkRenderWindowInteractor::New();

 interactor->SetRenderWindow(window);

 render->AddActor(actor);

 render->SetBackground(0.1,0.2,0.4);

 window->SetSize(200,200);

 interactor->Initialize();

 interactor->Start();

 cone->Delete();

 mapper->Delete();

 actor->Delete();

 render->Delete();

 window->Delete();

 interactor->Delete();

 return 0;

}

這裡值得注意的兩句是

interactor->Initialize();

 interactor->Start();

他們開始了整個程式的循環過程，接受你的輸入，并作出響應。
