[Insight-users] Polygonization algorithms, Marching Triangles

[Luis Ibanez]

Hi Dan,

There is a prototype implementation of Marching Cubes in the NAMICSandbox.

                  It is not "hidden"   :-)

The Sandbox is fully public

You will find it in:
http://svn.na-mic.org/NAMICSandBox/trunk/MarchingHypercubes/


This may not be the "Marching Triangles" that you are looking for,
but it may still be of interest.


    Regards,


        Luis
