[vtkusers] border cells

[Roman Grothausmann]

Hello Gonzalo,


You could use vtkGeometryFilter to extract the border polys. If You 
still need those up to some distance away from the surface You could use 
this "shell" as an input to vtkImplicitModeller which would give You a 
voxel image up to a specific distance which You could use to mask the 
original data. There might be a more elegant way not needing voxel data.

Hope this might help
Roman
