Smooth Mesh? Comparison to MATLAB

Support
1

Hello,
for my bachelor thesis I segmented a bone out CT volume data via MATLAB and exported it with stlwrite. For a comparison I’ve used 3D Slicer too. Now I noticed that the 3D-Slicer mesh is much more smoother than the mesh I’ve created with MATLAB (very pixelized). Now my question: Is there any algorithm in 3D Slicer which causes the smooth surface? Because the original volume data have the same resolution…

Smoothing may have been enabled in Segment Editor (see pic). You can adjust the amount of smoothing, or turn it off entirely.

Oh yeah, note that the default smoothing is (I think) 0.5.
