[Insight-users] question about save itkMesh

[Luis Ibanez]

Hi Quan,

You may want to use the class

      Insight/Code/Review/
         itkVTKPolyDataWriter.*


Note that you will have to insert a small
modification, since this class assumes that
the Mesh is a 3D mesh composed of triangular
faces.

In you case, however you have a polyline.

....

Note that the Curve2DExtractor *DOES NOT* form
lines. It only detects pixels that are good
candidate to be part of a line.  I assume that
somehow you are venturing to connecting pixels
with their close neighbors in order to form lines.


   Is that the case ?


     Please let us know,


       Thanks


          Luis
