[Insight-users] Isosurface using a different image pixel type? Baffled by generic programming.

[Luis Ibanez]

Hi Robet,


It is indeed very easy.

Simply pass your image through the ThresholdImageFilter
nd generate the binary image that the BinaryMask3DMeshSource needs.

For details, look at the ITK Software Guide


             http://www.itk.org/ItkSoftwareGuide.pdf


Section 6.1, pdf-page 165.


        Regards,


           Luis
