Show 3D Smoothing Algorithm

[aiacocca]

Hello! I was wondering what smoothing algorithm the “Show 3D” smoothing option uses in the segment editor.

Thanks!

The default smoothing algorithm is the flying edges, see

Pinter, C., Lasso, A., & Fichtinger, G. (2019). Polymorph segmentation representation for medical image computing. Computer Methods and Programs in Biomedicine, 171, 19–26. Redirecting

The experimental algorithm is SurfaceNets, see

New surface model generation method: SurfaceNets

We have now integrated the SurfaceNets isocontouring method into “Show 3D” functionality of the Segment Editor! The new experimental algorithm provides a ~7x speedup to the generation of surface models from segmentations compared to the default method (Flying Edges). The option can be enabled from the Show 3D menu in the Segment Editor.
