Hi Ben,
yes, that should work (maybe you got it working in the meantime, sorry for the
late response).
Better yet, you should also be able to just copy the vmtkcenterlines file from
the vmtk source, change relevant names (filename, module and class names), and
just use your updated script in a pipe with all the rest of vmtk. You can
pretty much customize vmtkcenterlines at your will this way, including the
seeding. Just keep the script in the current directory and you should be fine.
The only thing you have to remember is to replace
import vtkvmtk
import vmtkrenderer
import pypes
...
with
from vmtk import vtkvmtk
from vmtk import vmtkrenderer
from vmtk import pypes
...
Let me know if this works for you.
Best regards
Luca
