[vtkusers] Distinctive indexes on a vtkPolyData

[Li, Wen]

Hila,

Is vtkKdTreePointLocator::FindPointsWithinRadius going to help you?

You can exclude points within a specific radius and the rest points on the surface are beyond that value.

You are right about the point ids. neighboring points could have very different point Ids.

Good Luck,
Wen

Hi All,

I'd like to get some distant points on a surface (in this case, a head).
How do I know what the distance value should be?

Actually, in my program I use this type: vtkIdType and with a loop move on a vtkPolyData.
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 :-)


so, any idea how I should find indexes/points which are faraway from each other on a surface ?


Thanks in advance.

Hila
