Both look great, an evergreen and a deciduous. Now an iso-(ex)-forest
can be created!
Looking at the pine tree out my window, the bark looks a little skinnier
than this one, but that could just be the species. Also the bark seems
to "cup" out a bit at the bottom edges. So many different types, this
could be spot-on for all I know.
Wonderful work. I love isosurfaces; powerful and fun.
