True, and sometime people want to move data to other programs that does not read the image direction fields of NRRD (like Fiji). So volume needs to be resampled.
I don’t think that true: This is my original data:
Now I rotated with interaction widget to make it consistent with planes:
I have hardened the interaction transform, and used the crop volume with interpolation checked and the first evidence that it is not resampled, output dimensions are not changing:
And if you look at image directions of that cropped volume you can see it simply copied the transfrom from the original image:.
The only way I can make this work, if I volume render and set the ROI to image extends in the volume rendering and then crop. The image is resampled.
