As my mind wanders, so do my experiments. I've been meaning to do
something like this for quite a while, but just never did.
The scene contains three separate isosurfaces which make up the bark of
the stump. Since the functions for them involved blobbing and surface
displacement, I found it expedient to optimise the calculations a little
by adjusting their individual bounding boxes.
The heartwood is simply made of cylinders.
Lighting is nothing too special, just two light_sources; one a cruddy
area_light.
Comments, questions?

Why not isowood ? :-)

Interesting, I'm looking forward for whole forest.

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!

Nice. You know i tried something similar some time ago:

Hey, I think I like yours better :) The tree in yours is like a cedar,
wheras mine is a bit more piney. Your wood is more substantial, too. I
can almost feel it's roughness.
The flowers and grass are very nice indeed.

But your bark pattern looks very nice although i have the impression it
does not follow the transit to the roots.

Thanks.

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.

That looks really great. What did you use for the grass and flowers? The
stump wood is also quite nice.

Grass and flowers are meshes, you can find some more information on this
