[Insight-users] rotating data with in a 3D array

[rama]

Hi,

I am looking for a way to rotate data within a 3D array. I have a 3D 
array with dimensions X*Y*Z with each value being an integer in the 
range 0-255 which actually represents a gray scale 3D image.
Now I want to rotate the image in that array, by this I mean, I want to 
rotate the data with in that 3D array and store the result in the array 
of same dimensions.

I have come accross the MultiResMIRegistration example in ITK 2.0.0 
distribution. I have seen it rotating a 3D data set (array) to register 
with another 3D data set. I have seen its code but there is little help 
in it. I have also seen the Transform class in ITK. But it doesn't give 
any information about how to trigger the transformation and will it 
transform the whole 3D array in a single go.

Can anyone give an idea of how to do rotations on data with in a 3D array.

thanks,
Rama.
