[vtkusers] Sampling vtkImageData

[Steve Boyd]

Hi,

I want to interpolate a scalar value from my vtkImageData at various 3D
points.  Can somebody explain how I should do this?  

I've been trying vtkImageData::FindPoint(p3) where p3 is a given point. 
This gives a pointId which I can use to get the scalar data.  However,
I'm not sure what criteria FindPoint uses.  Maybe this isn't the correct
approach?

Sincerely,

Steve
