This is based on the Pythagoras tree. I used a triangular prism as the base, but
tapered the top so each iteration an equal volume would be added (rather than
triple). I added coloring to make it resemble a real tree. Do you think this
would look good on a fractal landscape next to an infinitely long coastline?

The trunk could be a bit longer, but overall I would say that this we 
have a winner. :-)

(You have one week to crank out that infinite coastline and enter it 
into this month's TC-RTC!)

Just what do you think you're doing, Dave?

Hey, cool.

I love fractals, and all things iterative.
Sponges, gaskets, automata, and strange topology.
May I add your source code to my pov-fractal collection? ;-)

Thanks,
Ian

Great idea for a stylized effect.  Almost reminds me of illuminated 
manuscripts.

I wonder if there is a way to texture the wood components, perhaps with 
transparent areas to the pigment, that would maintain the fractal 
generated feel, but read a little more convincingly as branches.

Thanks. The branches apparently go lower than the bottom of the trunk. There are
two ways to fix it: lengthen the trunk, and make the iterations scale down
faster. The problem with the first is it seems too inelegant. The problem with
the second is at the current scale, exactly the same amount of volume is added
each iteration, so it would seem wrong to change how much it scales. I'll
probable go with the first if I actually put it on a landscape, and make it
infinitely long.

How would I have a fractal landscape (with visible triangles so you could tell
it was a fractal landscape) and an infinitely long coastline? I suppose I could
make the border of the ocean slightly above the actual floor and have
no_shadows, so you can't quite tell. Is there any way I could make it so you
can see the ocean through the ground so I don't have to bother making the ocean
a little above?

Go ahead. If you post the source, attribute that part to me, but don't bother
with pictures. Should I put it on the POV-Ray Object Collection?

If I did that, I'd also have to make a texture for leaves that are shaped like
branches. There's no actual border between the branches and leaves. If you look
closely, the smaller branches start to get a little green.

What's this TC-RTC thing you keep mentioning? IRTC2?

:-D

Cool! Where might one find the source?

Hmm...I wonder what that tree would look like made of glass with photons 
turned on. <grins devilishly>

Thanks,
Ian

I don't entirely follow how you're implementing the landscape fractal.

In a pinch, you could make the land and sea one object, and use a 
texture map to give the water a shiny blue texture. I'm not sure if that 
helps you at all.
