[Insight-users] DeformableModelSimplexMesh example problems

[Luis Ibanez]

Hi Dženan,

Thanks for testing the builds in 32bits.

This certainly looks like a bug.

Please make an entry at
http://public.kitware.com/Bug/my_view_page.php

At this point it is unclear if this is an

* ITK Bug, or
* VTK Bug, or
* InsightApplications Bug...

So, please log it as an ITK bug, and make sure
that you mention your findings regarding 64bits
versus 32 bits.


The next step is to reduce this problem to
a very minimal case...


The center of the problem seems to be the
conversion of the ITK mesh to the VTK mesh.

You could take that piece of code out of the
InsightApplications code, and into its own
small file, and see if the problem can be
replicated there (in a 64 bits build).


I'm assuming that you would like to Adopt
this bug....    is that right ?


    Thanks


         Luis
