如何使netcdf情节喜欢c++的华丽服饰吗

Question

我试图让netcdf情节像什么华丽但我不确定如何获得这段代码

vtkSmartPointer < vtkNetCDFCFReader >读者= vtkSmartPointer < vtkNetCDFCFReader >::新();读者- > SetFileName (“C: /用户/ admin /桌面/ BOLTgui /螺栓/ test.nc”);读者- >更新();vtkDataObject * dataObject =读者- > GetOutput ();vtkDataSet *数据集= vtkDataSet: SafeDownCast (dataObject);vtkPointData * pointData =数据集- > GetPointData ();vtkSmartPointer < vtkContourFilter > contourFilter = vtkSmartPointer < vtkContourFilter >::新();contourFilter - > SetInputConnection(读者- > GetOutputPort ());contourFilter - > SetValue (0, 20);/ /设置感光度contourFilter - >更新(); vtkSmartPointer lookupTable = vtkSmartPointer::New(); lookupTable->SetNumberOfTableValues(256); lookupTable->Build(); lookupTable->SetTableRange(contourFilter->GetOutput()->GetScalarRange()); vtkSmartPointer colorTransferFunction = vtkSmartPointer::New(); colorTransferFunction->AddRGBPoint(0.0, 0.0, 0.0, 1.0); // blue colorTransferFunction->AddRGBPoint(20.0, 0.0, 1.0, 0.0); // green colorTransferFunction->AddRGBPoint(40.0, 1.0, 1.0, 0.0); // yellow colorTransferFunction->AddRGBPoint(60.0, 1.0, 0.0, 0.0); // red vtkSmartPointer mapper = vtkSmartPointer::New(); mapper->SetInputConnection(contourFilter->GetOutputPort()); mapper->SetLookupTable(lookupTable); mapper->UseLookupTableScalarRangeOn(); mapper->ScalarVisibilityOn(); mapper->SetScalarModeToUsePointData(); mapper->SetLookupTable(lookupTable); mapper->SetLookupTable(colorTransferFunction); vtkSmartPointer actor = vtkSmartPointer::New(); actor->SetMapper(mapper); vtkSmartPointer renderer = vtkSmartPointer < vtkRenderer>::New(); renderer->AddActor(actor); vtkSmartPointer renderWindow = vtkSmartPointer::New(); renderWindow->AddRenderer(renderer); vtkSmartPointer interactor = vtkSmartPointer::New(); interactor->SetRenderWindow(renderWindow); sf::WindowHandle handle = window.getSystemHandle(); renderWindow->SetWindowInfo(reinterpret_cast(handle)); interactor->Start(); //While loop glBegin(GL_TRIANGLES); glPointSize(0.111f); // Calculate scaling factor float scalingFactor = 1.0f / 2.111f; vtkSmartPointer data = vtkDataSet::SafeDownCast(reader->GetOutput()); for (vtkIdType i = 0; i < data->GetNumberOfCells(); i++) { vtkCell* cell = data->GetCell(i); vtkPoints* points = cell->GetPoints(); double point1[3]; double point2[3]; double point3[3]; points->GetPoint(0, point1); points->GetPoint(1, point2); points->GetPoint(2, point3); // Set the color for the first vertex glColor3f(1.0f, 0.0f, 0.0f); // Scale the point coordinates to adjust the size glVertex3f(point1[0] * scalingFactor, point1[1] * scalingFactor, point1[2] * scalingFactor); // Set the color for the second vertex glColor3f(0.0f, 1.0f, 0.0f); glVertex3f(point2[0] * scalingFactor, point2[1] * scalingFactor, point2[2] * scalingFactor); // Set the color for the third vertex glColor3f(0.0f, 0.0f, 1.0f); glVertex3f(point3[0] * scalingFactor, point3[1] * scalingFactor, point3[2] * scalingFactor); } glEnd();

这段代码目前显示netcdf这样的数据但我试图在opengl渲染netcdf数据我需要做什么来修改代码来呈现netcdf数据华丽服饰的阴谋
