hi ting chen.
I agree with you , balloon force by itself is quite unstable. A snake =
usually require other forces to guide a deformable mesh to the contour =
of interest such as gradient force or others based on curvatures and =
smothness constraints.
What are your plan for this class ? are you going to resume the =
implementation , or have you given up for ever . I you go on , I would =
be interested in joining you to implement some other features for a more =
general 3D snake.
by the way , the link to your publication on your home page is broken , =
you should redirect it to your pictures directory as the file seems to =
be located there.
alex.

HI! I have written a itkdeformable3DMeshfilter and a =
itkballoonforcefilter for 3D and 2D deformable fitting. I give up =
itkballoonforce3Dfilter because it seems 3D ballon has problems in =
clinical applications (difficult to maintian topology)

Subject: [Insight-users] 3D mesh deformation ?
hi everyone.
By browsing into the doxygen generated docs, I found references to =
(almost) 3D deformation mesh classes, and especially a class named =
BalloonForce3Dfilter which implements a 3D snake.
But I didn't see any references to it in the brand new software =
manual neither couldn't I find any example related to this class.
Is there any example I missed ?
Is there any documentation (else than html or source code) to come ?
and, last but not least, are other 3D segmentation algorithms' =
implementation scheduled ?
by the way , huge work on the software manual , it's awesome ! (in =
several way much better than the vtk user manual :-) )
alex.
