Okay, I added the leaf macro. Yes, I know, the leaves need better
texturing, and I'm using what are obviously maple leaves with what is
obviously not maple bark. Please tell me your praise/criticism and
suggestions to make it better.
I modelled the maple leaf in sPatch, not realizing the strain that many
patches would put on POV, so I later manually copied the outline points
of the leaf into a cubic_spline prism in POV.
Render time: 7:34
(4-way splits, 4 levels, 16 leaves per branch)
memory: forgot to check :-(

BTW, this is 100% original work, I haven't even glanced at anyone else's
tree macros :-)

Congratulations. I wish I could get down to writing a useful macro and
object generation include. If you want my opinion, it looks cartoony.
Perfect for a setting with blob-men. =) What parameters can one control in
the creation of the tree?

The cartooniness I believe can be toned down with proper texturing, which this
"tree" is far from.
PARAMETERS: Start-coords of trunk, end-coords of trunk, recursion level,
number of branches at each split, ratio of diameters at start and end of
branch (cone factor--redundant, should be same as child-diameter-ratio), ratio
of length in child branches, ratio of diameter in child branches, average
offset angle of child branches from parent branches, randomization factor of
branch endpoints, number of components per branch, "crookedness" (not yet
implemented), "bumpiness" (what this tree uses), radius of trunk, leaf density
(leaves per branch), leaf size (scale factor), leaf object definition, and the
four seed values. If you try to put all of these into one macro, POV complains
that it's too many, so I made a branch macro and a leaf macro, the leaf macro
is like the branch macro, but it skips the actual "add component" line and
instead has an "add leaf" line if the recursion level has reached zero. In the
leaf macro I can eliminate crookedness, bumpiness, radius, and a couple seed
values. (The rest are needed to determine the start and end coord's of the
branches.)

Hmm, that gave me an idea... as the branch macro executes, it stores
level-zero coordinates in an array for the leaf macro.

The tree is looking better. I like the texture and and leaf pattern. Not the
most realistic, but I like this tree. I still would like to see more
variation in the lengths of branches.
