- Create a copy of our classy pic3D.nrrd
- Open the nrrd file in the texteditor and manually change the spacing to something below 1 (e.g. 0.1, 0.1, 0.3)
- Try a simple 3D interpolation

--> Interpolation result is strange and unusable
I have another image (standard direction) with spacing of 40, 40, 48 and also get strange results. See screenshot3. Here, the manually segmented layer is not fully included in the interpolation.
Guys,
This is a major issue for us. The segmentation module is unusable with 2014.10.
-F
I will have a look at that for the upcoming release.
@Felix: are there other issues regarding the segmentation plugin? You wrote that it is unusable with 2014.10. Or was did you mean that the 3d interpolation is unusable?
I fixed the strange results for the images with a very small spacing.
I could not reproduce the bug where the manual segmentation is not fully included in the interpolation.
There is still an issue for images with bigger spacing. It seems that the distance values are calculated for the whole image instead of just along a narrow band. I will investigate that

Fixed spacing calculation for distance image
Now the spacing can have a float value which is needed in case of reference data with a very small spacing
2015-03-30 11:02:33 Andreas Fetzer [765a16]
Fixed the calculation of the off-surface points
Now the normals used for the calculation are scaled with the spacing of the
distance image.
Previously the normals always had the size of 1 mm, which is too small or too big
in case of images with a very big or small spacing

Fixed normal calculation.
The normals were not normalized properly.

Fixed weird results for images with a very small spacing
The reason was that the narrow band calculation of the distance image values
used a too small threshold.
