<div dir="ltr">Hi All,<br>
<br>
I'd like to get some <b>distant points</b> on a surface (in this case, a head).<br>
How do I know what the distance value should be?<br>
<br>
Actually, in my program I use this type: vtkIdType and with a loop move on a vtkPolyData.<br>
I tried to guess a number (5000), presented the points on the surface but realized that even that those points look very close, their indexes are faraway from each other- so I guess that I don't have a clue about it :-)<br>
<br>
<br>
so, any idea how I should find indexes/points which are faraway from each other on a surface ?<br>
<br>
<br>
Thanks in advance.<br>
<br>
Hila <br>
