[vtkusers] need some useful 3D data to test

[Shwu Ping Vong]

Hi vtkusers,

I have built a small tool that uses volume rendering technique.  All
along I just used "ironProt.vtk" that comes with vtk to test.  However,
since the final goal for my tool is to analyse streaming data,  I need
some other 3D dataset for testing, preferably some weather data, but not
necessary.  Can anyone out there provide me with some data or point me
to some websites?

Thanks,
