Sounds good.  How would you tie the file data to the box grid? Can you post your
test code?  Variable ior would be really good, but I can live with variable
scatter. :)

I found a good link at http://paulbourke.net/miscellaneous/df3/

My orginal data is 3d, so the link looks very promising.

I assume DF3 is the only supported file format?  Would be nice if DF3 supported
floats, but gee, you can't have anything.  I probably could write a matlab
float2df3 util, but there's some 'c' code posted on the linked wavepage.

Life is good,

Thanks y'all for the posts.
