SegmentEditor HollowEffect - Shell thickness

Support
1

Operating system: Windows 10
Slicer version: 4.10.1

As I was trying to understand the parameters (especially the shell thickness) of the HollowEffect. I created a cube of 7x7x7 and applied the effect with a 3x3x3 kern size (2-4 mm). I am sure that the kern size is the smallest one, but the result had a thickness of 1 pixel (1 mm and not 2-4 mm). and as well if I determine the shell thickness between 4 and 6 mm, I get a cube with a thickness of 2 mm (2 pixels).

I am useing a segment’s spacing of 1 mm per pixel.

may I politely say that maybe the “shellThicknessMm” should be by 2 divided, if it’s not the case, could you please explain the results to me.

I am thankful for your answer

Thanks for reporting this. Indeed, while the used kernel size was correctly displayed, it was not the closest match to what was requested. I’ve fixed this now. The fix is available in Slicer Preview Release that you download tomorrow or later (revision 28547 or above).
