Choose branch type before hitting flag. Try different angles, wiggle, hit flag again. For our hand drawn versions, hit "Pencil Drawing."
Patterns repeat at smaller scales (fractal). Blossoms turn to green leaves then fall colors, then fall & blow! All three tree types from one set of code! Blossoms-->leaves (wait for it) & 3 biotypes: Bifurcates: splits into 2 new branches ("sympodial") Trifurcates: 2 new branches + 1st = 3 ("monopodial") Fibonacci tree: splits asymmetrically ("sympodial-monochasium") In trifurcating, the main branch continues between two new ones. Pine trees are an example. Botanists call it "monopodial." They call bifurcating (forking) "sympodial." The Fibonacci sequence results because branches must mature before splitting, resulting in asymmetrical branching, the most common tree pattern seen. All are fractal, similar across scales. Most trees are not just monopodial or sympodial, but a mix ("sympodial-monochasium"). This mix much like bifurcating but the splitting starts earlier on one side, resulting in a Fibonacci sequence of branches as the tree grows up. See our previous tree models in scratch, under "Bifurcating vs. Trifurcating Tree" and also "Geometric vs Fibonacci" trees, "fractal fall foliage" and others. This model here has the advantage of showing all three types with a few changes in code.
