Hi, Like the title say, I would to like to add some attributes to a vtkPointSet (vtkPolyData and vtkUnstructuredGrid). The attributes are vector(2D, 3D,...) field or scalar field.
For a scalar Field, If I want to add an attribute to the cells , I do: output->GetCellData()->AddArray( data) and output->GetPointData()->AddArray(donnees); for the points For the moment it is ok, because I can select them in Paraview. But now, I have a 2D (or 3D) vector field (velocity) and I would to add the velocity field for the points or the cells. How can I do that ? Moreover, if I want to show somme arrow (to show the direction of the vectors) should I use the glyph filter ? Thank you.
