New segment editor effect for creating hollow objects


(Andras Lasso) #1

Making a solid segment hollow is useful in many applications, such as creating 3D-printable vessel walls from contrast-CT volumes.

While it was possible to create hollow segments in 3D Slicer by using Margins and Logical operators effect, it was not very convenient.

A new effect - Hollow - has been added to Segment editor to create hollow objects from solid objects in one simple step.

Thanks a lot!

Thank you for the quick reply!
The SegmentEditorEffects extention had been installed in the software.Even if I downloaded the,add its path into the additional module and restart 3D Slicer,the button of the hollow have not shown in the Effects file as below.What is the reason about this?Otherwise,there is a file named “”,what is the meaning about is?%E6%97%A0%E6%A0%87%E9%A2%98

If you installed SegmentEditorExtraEffects extension for Slicer-4.8.1 before, then you need to update it (or uninstall and install it again) to get the new effect.

For manual install, it is not enough to copy a single file but the entire content of SegmentEditorHollow folder, including subdirectories. The folder containing must be added to Additional module paths.
