-> the resulting model has holes.
Source image was Pic3D.pic
segmentation is available here: /home/jochen/temp/pic3d-segmentation-poly-holes.pic
see attached screenshot.

The holes occur at at area where the segmentation reaches the border planes of the segmentation-image (see attached screenshot).
Could be that I selected "Auto crop segmentation" before creating the surface. This would explain the holes.
In AutoCropImageFilter::ComputeNewImageBounds() m_RegionIndex and m_RegionSize should be changed to a value increasing the bounding volume by one pixel. This way the generated surface will not contain any holes, unless it is directly located at the border plane of the original image.

FIX (#3145): increasing cropped image size to close holes while generating a surface
To close the holes while generating a surface after copping the segmentation I modified QmitkSegmentationView. Added the method IncreaseCroppedImageSize() to pad the image after cropping.
Trying to resize the image in AutoCropImageFilter did not work. Strange side effects occurred within QmitkImageStatisticsView.
