surface_是模型，self_intersected_list是模型里需要特殊标记的cell

void ShowPolydata(vtkSmartPointer<vtkPolyData> surface_,QList<quint32>  self_intersected_list) {qSort(self_intersected_list.begin(), self_intersected_list.end());self_intersected_list = self_intersected_list.toSet().toList();unsigned char color1[3] = { 255, 0, 0 };unsigned char color2[3] = { 0, 0, 0 };vtkNew<vtkUnsignedCharArray> cellColor;cellColor->SetNumberOfComponents(3);for(quint32 i = 0; i < surface_->GetNumberOfCells(); i++) {if(self_intersected_list.contains(i)) {cellColor->InsertNextTypedTuple(color1);} else {cellColor->InsertNextTypedTuple(color2);}}surface_->GetCellData()->SetScalars(cellColor);vtkNew<vtkPolyDataMapper> polydatamapper ;polydatamapper->SetInputData(surface_);vtkNew<vtkActor> actor ;actor->SetMapper(polydatamapper);actor->GetProperty()->SetOpacity(0.1);vtkNew<vtkRenderer> renderer;renderer->AddActor(actor);renderer->SetBackground(0.2, 0.2, 0.2);vtkNew<vtkRenderWindow> renwin ;renwin->AddRenderer(renderer);renwin->SetSize(800, 800);vtkNew<vtkInteractorStyleTrackballCamera>style ;vtkNew<vtkRenderWindowInteractor> rendererwindowinteracrot ;rendererwindowinteracrot->SetInteractorStyle(style);rendererwindowinteracrot->SetRenderWindow(renwin);rendererwindowinteracrot->Start();
