Hi,
I would like to display the ID numbers of my bodies. They are saved
as a Point Data as follows from vtkUnstructuredGridWriter. Is there a
way to display the IDs as texts using Paraview? I've been trying out
different Filters for hours but am unsuccessful.
vtkSmartPointer<vtkFloatArray> spheresId =
vtkSmartPointer<vtkFloatArray>::New();
spheresId->SetNumberOfComponents(1);
spheresId->SetName("id");
vtkSmartPointer<vtkUnstructuredGrid> spheresUg =
vtkSmartPointer<vtkUnstructuredGrid>::New();
FOR EVERY BODY:
spheresUg->SetPoints(spheresPos);
spheresUg->SetCells(VTK_VERTEX, spheresCells);
spheresId->InsertNextValue(b->getId());
spheresUg->GetPointData()->AddArray(spheresId);
END FOR
vtkSmartPointer<vtkXMLUnstructuredGridWriter> writer =
vtkSmartPointer<vtkXMLUnstructuredGridWriter>::New();
string fn=fileName+"spheres."+lexical_cast<string>(scene->iter)+".vtu";
writer->SetFileName(fn.c_str());
writer->SetInput(spheresUg);
writer->Write();
Yours faithfully,
Boon
