[vtkusers] indexes on a surface

[Hila Hiler]

Hi David
thank you for the reply.

I'm sorry but I've misunderstood your answer.
Is the problem with the surface which includes outliers?
My surface is clearly structured in a specific location (at least no
outlier is presented)
so why the extracted points aren't on the surface?

how it's possible to check where an index is located on a surface? (is it
posible to insert my surface and an index and the point will be presented
correspondingly?)


Best Regards,
Hila
