[Insight-users] how to generate 3D mesh

[Luis Ibanez]

Hi Longfei,

This class will not genereate tetrahedra for
a volume. It only generates surfaces.

You will find classes for generating tetrahedra
in VTK. You could convert your ITK image into
a VTK image and then use one of such VTK filters.


Regards,


   Luis
