I've recently hacked together an implementation of
the Marching Cubes algorithm for "surface-based"
volume rendering (some would prefer to call it "surface rendering").
It seems to be working ok with the simple test data that
I created. The next step is to test it using real volume data.
There seems to be several popular data sets that appear
in many volume examples and literature (i.e. the famous MRI
brain scan of an anonymous woman [I think she has a nickname],
the tree sloth, the skulls from the Drebin et. al. and Levoy papers).
Since this data "appears" to be passed around rather freely,
I was hoping that someone could tell me where I might find some
of these sample data sets for testing my software. Hopefully,
it is public domain and can be acquired via 'anonymous FTP".
I suspect that NCSA will have some sample data sets with their
new ISOVIS software.
Any leads or suggestions would be much appreciated.
Thanks, in advance.

During the 1st Workshop on Volume Visualization (Chapel Hill, NC) people decided that is was a good idea to be able to compare various algorithms. This lead to 2 "public domain" tapes with various volume sets, including MRI and CT datsets. These tapes are distributed by the SoftLab of the University of North Carolina, Chapel Hill. You may be able to get more information from Graham Gash of the Computer Science Department (gash@cs.unc.edu).
