[Insight-users] help generate mesh of binary image

[Luis Ibanez]

Hi Longfei,

The complete documentation of the BinaryMask3DMeshSource
class is available at:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1BinaryMask3DMeshSource.html

For an example on how to use the class you can look at

    Insight/Testing/Code/Algorithms/
              itkBinaryMask3DMeshSourceTest.cxx


Regards,


   Luis

>      I have used the Update(),but the retun numbers of poits and cells are zero.it seems that there are no mesh generated. Could you tell me whether there are some other methods? And i want to learn to use the codes of FEM, but there are no guides. Could you tell me how to muster it! Very thank you!
