[vtk-developers] vtk-developers Digest, Vol 95, Issue 51

Wed Mar 28 17:06:06 EDT 2012

Hi  Aashish,
I agree with your comments but consultation with the wider community is
essential.
With regard to the TCL examples for the books, there seem to be some
missing datasets.
As I said earlier I am glad to help in converting them to Python. It would
be a good idea to set up a repo. I am sure the C++ code will also need
looking at too.
