VTKでBoundingBox計算しない設定

方法SetUseBounds

vtkActorのSetUseBounds(false)を使う方法で、ActorのBoundingBoxを計算しないことができます。

サンプルコード

vtkSmartPointer<vtkLineSource> lineSource = vtkSmartPointer<vtkLineSource>::New();
lineSource->SetPoint1(0, 0, 0);
lineSource->SetPoint2(1, 1, 1);


vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection(lineSource->GetOutputPort());

vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
actor->SetVisibility(true);
actor->SetUseBounds(false); // BoundingBox計算しない

vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor(actor);

vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);

vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);

renderWindow->Render();
renderWindowInteractor->Start();
