[Insight-users] Smoothing displacements over a surface

[Tom Vercauteren]

Hi Andriy,

The following IJ paper provides code to smooth displacement fields on
spherical meshes:
http://www.midasjournal.org/browse/publication/662

Hopefully, it might help you implement smoothing on arbitrary meshes.

Hope this helps,
Tom
