Hi, all<br>
<br>
I am trying to get some of the points from a polydata model, then use these<br>
points to form a new polydata model that has lower resolution than the<br>
original one.<br>
<br>
My question is, is there any method in VTK can help me to generate polygons<br>
for these points?<br>
<br>
Thank you very much.<br>
<br>
Best regards<br>
