Sounds great! Would be nice if this code were part of VTK. Quite a
while ago there was talk of creating a more advanced data file format
for VTK that would support more features. There was also talk of
streak lines etc. Here are a few thoughts I've had. They are still
thoughts and I'm not going to have time to implement anything either.
Effectively this is a wish list. Just in case someone is listening.
1. A slightly more intelligent VTK file. Maybe an additional file
format that allows for a more flexible syntax with scope for multiple
datasets, something like a #include etc.
2. I guess Luca's classes handle integration over time. So that
should be already done.
3. The ablity to use zipped VTK files. Would this be useful or are
binary files good enough? Now that zlib is distributed as part of
VTK this should not be a problem to implement.
