Thanks a lot Sven,<br>I could generate vector plots. Still trying to find a way to do 3D contour plots for my scattered points. As you said I need to have a mesh and to interpolate my scalar value to nodes of that mesh. Does anyone have an idea to do that? <br>

Nima,<br>
<br>
Your first question has been discussed last month on this list, have a look at<br>
<a href="http://markmail.org/message/36223zg4uleibiyj" target="_blank">http://markmail.org/message/36223zg4uleibiyj</a>. David found the time to put the<br>
question in FAQ style into the ParaView wiki. So, you can also look at<br>
<a href="http://www.paraview.org/Wiki/Display_points_and_normals_from_a_plain_text_%28x_y_z_nx_ny_nz%29_file" target="_blank">http://www.paraview.org/Wiki/Display_points_and_normals_from_a_plain_text_(x_y_z_nx_ny_nz)_file</a><br>
<br>
I haven't faced the problem yet you describe in your second question. I'm<br>
guessing you'll have to import your scattered data into ParaView (e.g. as CSV<br>
data) and somehow come up with a regular grid in ParaView. This might be<br>
possible using a Programmable Source or Sources - Data Object Generator, but I'm<br>
not sure of that. Maybe someone else can point this out. Once you have a regular<br>
grid, use the Resample with Dataset filter to interpolate your point data set(s)<br>
to the regular grid and apply the Contour filter.<br>
<br>
Hope this helps.<br>
