Glad that helped, Eric.<br>
<br>
Well, if you have the connectivity you can just write the surface
cells (triangles, quadrangles) like you did with the vertexes. If
you don't have the connectivity then I do not know, but I'm sure
someone on the ML will be able to help.<br>

<div>Thanks Martin. That works pretty well. <br>

I might add that I am scripting in C++ but I was quickly able
to translate. <br>

I see the output shows up in Paraview as a ton of points. How
may I proceed to make it a 'surface' which connects these
points? (the data set is a wing).<br>

Paraview only displays cells, not points.<br>
<br>
There are at least two solutions:<br>
- When you write the ugrid file, you can add vertices,
which are cells containing a single point, using something
like:<br>
<blockquote type="cite">cell = vtk.vtkVertex()<br>
cell_array = vtk.vtkCellArray()<br>
for k_point in
xrange(ugrid.GetPoints().GetNumberOfPoints()):<br>
cell.GetPointIds().SetId(0, k_point)<br>
cell_array.InsertNextCell(cell)<br>
ugrid.SetCells(vtk.VTK_VERTEX, cell_array)<br>
for k_array in
xrange(ugrid.GetPointData().GetNumberOfArrays()):<br>
ugrid.GetCellData().AddArray(ugrid.GetPointData().GetArray(k_array))<br>
</blockquote>
- Otherwise, if you have only points in your ugrid, you
can glyph them in paraview, using for instance a sphere
with fixed small diameter.<br>

<div>I have a raw data set of X,Y,Z coordinates as
well as a set of scalars (lets call them A, B,
C) which are stored at the aforementioned
coordinates. I use vtkUnstructuredGrid to create
the domain, but when I go to open the .vtu file
in Paraview I see that there aren't any cells to
visualize. </div>

<div>My question is- how do I go about providing
'cells' which use these points as cell-centers?</div>
