<div dir="ltr"><div><div> Hello,<br>Even though I am able to obtain some data by first generating grid using "Delaunay3D" and then adding "Probe Location". But the problem is that these data that I obtained are questionable.<br>For example,<br>The coordinates of probe points is: <br>
<table border="0" cellspacing="0">
<colgroup span="3" width="61"></colgroup>
<tbody><tr>
<td height="17" align="right">-64</td>
<td align="right">0</td>
<td align="right">15</td>
</tr>
</tbody></table>
while the coordinate property (paraview treats all data including property data like velocity, density and coordinate as field data) interpolated based on probe location and grids that was generated is:<br>
<table border="0" cellspacing="0">
<colgroup span="2" width="91"></colgroup>
<colgroup width="52"></colgroup>
<tbody><tr>
<td height="17" bgcolor="#FFFF00" align="right">119</td>
<td bgcolor="#FFFF00" align="right">0</td>
<td bgcolor="#FFFF00" align="right">945</td>
</tr>
</tbody></table>
<br></div>They are obviously different. I am not sue whether the "probed" value are values at the probe location computed by interpolation or not? It seems that the interpolation is did in a incorrect way and gives me some questionable data. <br><br></div>Is it possible that I can add probe locations without grids (the probe would be interpolation purely based on point data) and define my own way of interpolation, For example I can define kernel based collocation type of interpolation. Do you think this is possible (feasible) in paraview?<br><div><div><div><div><div><br></div></div></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">2016-02-12 12:58 GMT-05:00 曹智选 <span dir="ltr"><<a href="mailto:hitcaozx@gmail.com" target="_blank">hitcaozx@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Thank you for your help.<br>1) As you said, it is not necessary to use "Resample

<div>The "Probe Location" and the "Resample With Dataset" filters actually use the same code underneath the covers. The only difference is how the geometry source is inputted (internally generated points for "Probe Location" and another dataset for "Resample
With Dataset"). Also "Probe Location" is marked to by default show the results in a table view. However, you can show the results of "Probe Location" in a 3D view as well. Just select the 3D view and turn on its visibility.</div>
</div>
</div>
<div><br>
</div>
<div>Anyway, the point of all that is that it should be unnecessary for you to run the "Resample With Dataset" filter. You should get the same data from the output of the "Probe Locations" filter.</div>
<div><br>
</div>
<div>If all the field data in the output from "Probe Locations" are zero, then there is some reason why the filter could not find field data at the selected points. Once common problem is that the points are not actually located within the volume of your data.
If your input data is actually a surface, then this is likely as it is hard to place points exactly on the surface. Another cause for problems that recently came up on the mailing list is issues with using an unstructured grid dataset that has voxel-type cells
in it. The thread is captured here: <a href="http://markmail.org/message/t5vbs7opn43wtkdw" target="_blank">http://markmail.org/message/t5vbs7opn43wtkdw</a>.</div>

<div>
<div>Hello,<br>
</div>
I am trying to probe point based data with Paraview. <br>
</div>
What I did is:<br>
</div>
1) Create probe points with "ProbeLocations"<br>
</div>
2) Then use "Resample With Dataset", choose input as the data that I have already had and source as "ProbeLocations" that I created in the previous step.<br>
<br>
</div>
The trouble that i have is: All field data including coordinates are all zero.<br>
<br>
</div>
Could someone help me out?<br>
<br>
</div>
Thank you very much!<br>
<br>
