Re: Three dimensional Polyfillv

What if you took your (3,n) values and, for each slice in your data
volume, find the subset of the n points that fall on (or near enough
to be considered "on") that slice?  Then you could use polyfillv on
that slice.  I haven't done this with quite the data you have, but
that is the method that I use to create 3D ROIs out of multiple 2D
ROIs.
