[Insight-users] rotation of region

[Felix Schwenk]

hi,
i'v got a 3D image containing one region with value 1 everything else 
is 0. when i try to rotate the region using QuaternionRigidTransform 
it gets holes containing 0 values. this is, i guess, because of
interpolation.
is there any good way around this? i thought of converting it into a
mesh or something, 
then rotating it, is this a good idea? is there any better?

felix.
