I've used it for my work with Sun-Earth Connection/Divsion, primarily  
as a tool for examining dataset features before exporting isosurface  
meshes to a more powerful graphics rendering package.  I've used it  
under MacOS X, Linux and IRIX.

When you have real 3-D data, which I guess means a model in most of  
astrophysics, I find it very useful.  You can also script processes  
with it using Python to make simple animations.  Currently it uses a  
bit of a hack to handle time-varying volumetric data.

The biggest headache is trying to get data into the VTK format.  I've  
got a few python scripts that will construct unstructured grids,  
polydata, etc. for some datasets, but the files tend to be huge (I  
usually use the text format so I can examine them more carefully).

My $0.02 worth,
Tom
