Hi! I am experiencing a similar issue. What exactly do you mean by ‘as it wouldn’t be a linear interpolation anymore’? In my use case, I compared the pytorch interpolation result to the scipy.zoom(order=1) result, and they are very different. Specifically, the pytorch interpolation function extended the intensity distribution of the original volume, which I really don’t understand since I was just using trilinear interpolation. The range of the interpolated values should be confined within the range of the original value, right?
