1. Generation of a Douglas Fir using DLA David Blanco
Douglas Firs exhibit some fractal geometry, allowing for simulation via diffusion-limited aggregation
Use a “lattice” as a growth base, and fill in with 1d leaves.
In a generic simulation, the leaves will build to the top of the tree, then go back to the trunk and fill in
Different styles of trees require different lattices and different leaf fill ins.

3. Almost there...

4. Symmetrical Branches
Traditional tree shape, not much branch growth, but good overall shape
Something Charlie Brown would be very happy...er, sad with.

5. Asymmetrical Branches
Off set branches made manually, alternating every 40 spaces
Overall, better branch growth, but less volume
