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?

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,

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.

How's this? I feel like the trees are too big, bit it's hard enough to tell
their fractal nature already.
I figured out a way to make the fractal coastline. I could make a "cone" with a
base shaped like the coastline and skew it so the point is at the camera, than
clip the land by the inverse of the "cone". That would keep the ground from
blocking the view on that part.
Also, I'm considering adding quantum weather butterflies (see
http://wiki.lspace.org/wiki/Quantum_weather_butterflies). I figure it would be
better to give them Mandelbrot set-shaped wings (the cardioid part) with Julia
set patterns (see http://en.wikipedia.org/wiki/Image:Mandelbrot_and_Julia.png)

Use an isosurface for that ground.

A fractal landscape is done by starting with one large triangle (or square) and
cutting it into smaller ones, each moved slightly from where it should be.
http://en.wikipedia.org/wiki/Fractal_landscape has a good picture. How would I
do that if the ground was an isosurface?

That's only one of many ways to get your fractal shape.
With an isosurface, you can use some functions, like f_ridged_mf...
