<br>
<br>
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.<br>
<br>
Hope this might help<br>

Hello,<br>
<br>
Is there a way of knowing if a cell belongs to the border of a polydata?<br>
<br>
In fact I need to extract all the cells that are at most 0.5 mm from the<br>
border of the polydata, any ideas?<br>
<br>
Thank you!<br>
<br>
