[vtkusers] Resampling an image data

[Mathieu Coursolle]

Hi VTK users,

I have a 2 vtkImageData (3D datasets) which are defined in 2 different  
coordinate systems. I know the linear transform to map from one to the  
other space. What would be the simplest way to resample the second  
data set so that they can be blended together.

I tried to use vtkImageReslice and to set it a vtkTransform, but there  
are a lot of inputs I am not sure to understand. For example, do I  
need to set SetInformationInput?

Thank you!

Mathieu
