Except for the color, it looks very much like red-pine to me.  Very nice.
I've often thought about making a red-pine forest scene.  But then I have
lots of ideas that I never seem to have time to implement... :-(

Cristoph Hormann had a similar stump a month or two ago as well.  I'm
looking forward to seeing more examples from both of you.  Are you using any
of Christoph's libraries?  isowood, isocsg, etc.  If not, they may simplify
some coding.  Personally, I find isosurfaces extremely difficult to deal
with otherwise.

Keep up the good work!
