Here is my first attempt at a cactus in MegaPOV(inspired by some
discussions in the thread "A clock"), it uses trace() and an isosurface.
The texturing still needs a lot of work...

It's real good. A bit on the bright side but otherwise cute.
The translated nickname for this kind of cactus is
mother-in-law chair
:-)

I love it! When you say you used trace, I guess that the whole cactus is
made with (pseudo)maths, and no hand-positioning of primitives, right?
That's the way (aha-aha) I like it (aha-aha)...

I used trace() to place the spines, the body of the cactus is a single
isosurface. The spines were placed by #while() loops, and nothing was
hand positioned(well, the starting position of the "spine scanner" and
the height of the isosurface were...).

Looks great how it is but you are right, just a little bit of texturing
would go a long way on this. I am just baffled at how this is one
IsoSurface! I suspect that there is some sort of a sin()/cos() thing going
on, but dang if I can figger it.
There is a -lot- more to IsoSurface than I will ever be able to learn.

Outstanding!! Most realistic looking real-life thing. I think the thorns
or pricks or whatever you want to call them is what makes it realistic - the
randomness, as well as the soft shadows. Well done!!

That looks great. If I can't come up with a good cactus could you share the
code ? :)

Maybe just a slight granite normal scaled bigger in y than in x and z ?
I'll go fech some books since I haven't taken a better look at the "texture"
of real cactii :)

This is a great image: what a piercingly fine cactus! How are you ever going
to do better?

I'm impressed!
I had thought that trace wouldn't work with the isosurface, I was obviously
wrong!
Which is a good thing as I've been experimenting with ridged multifractels
as a means of creating landscapes - now I can place things on them!
