[vtkusers] VTK/MayaVi and AMR datasets?

[Tom Bridgman]

Terry,

I have some familiarity with ChomboVis - I share an office with a person
working with the NASA CT (Computational Technologies) group.  I believe
we have some older version of it installed on one of our IRIX systems. 
He points out the drawback of currently it is only pre-VTK 4.0 and we're
already using VTK 4.2.  Also, recently we obtained successful builds of
VTK and MayaVi on MacOS X and I'd like that capability so 'work from
home' is occasionally an option.

One of the current AMR datasets I have is from a BATS-R-US magnetosphere
model but I'm uncertain of the specific format since the group that sent
me the data also sent me a reader in IDL.

While I'd like to use MayaVi to slice the data for the details I want,
writing a simple Python script that pops up a VTK window to check my
results is also an option.  I haven't heard about this possible
conversion tool so I'll have to investigate that at some point.

Thanks,
Tom
