[Insight-users] writing mesh

[Luis Ibanez]

Hi Thomas,

Then Mesh writer of Spatial Objects doesn't use the same
fileformat as VTK.

The class that you may want to use is in the directory

          Insight/Code/Review
             itkVTKPolyDataWriter.h
             itkVTKPolyDataWriter.txx


Note however, that a much better way to proceed is to
use the Antialias filter in your binary image, and then
save the smoothed image as a MetaImage or a .VTK image.

Then read the image in ParaView, and use the Contour
filter in ParaView for generating the surface.



     Regards,


        Luis
