[Insight-users] Problem Using the itkBSplineScatteredDataPointSetToImageFilter on Win32

[Otmane Lahlou]

Hi Nick,

Thanks you for your feedbacks,

Can those precision values issues be related to the parameter 
m_NumberOfLevels ?
In the test i sent  m_NumberOfLevels  is equal to 10,  and for this 
value the exception is thrown.

In general, the exception is thrown also for  m_NumberOfLevels values  > 5.
But it runs well for m_NumberOfLevels <=5.

Can you give me a brief explication about that, and the way to choose 
the right NumberOfLevels  value ?

Thank you

Otmane

Although I tried to accommodate calls on the open boundary, due to precision differences, you're getting that error on Win32 vs your Linus distribution.  What you want to do is ensure your query of the B-spline object value is inside the B-spline domain, e.g. 511.9999 instead of 512.
