        Santosh,

<br><br>The default tolerance for ray-cell intersection is too large for your

<br>dataset. The selection algorithm shoots random rays from the test

<br>point through the surface. Since each call to Update generates

<br>different random rays, you see varying results. Decrease the tolearce

and you will get consistent results.

<br><br>The default tolerate is .001. Try .00001 with your data:

<br>filter.SetTolerance(.00001)

<br><br></span>Bill
