**The definitions show how to create 2D Branching Structures using RABBIT.**

More about Branching Structures: http://algorithmicbotany.org/papers/abop/abop-ch1.pdf

The meanings of the symbols:

Fmove forward at distanceL(Step Length) and draw a line

fmove forward at distanceL(Step Length) without drawing a line

+turn leftA(Default Angle) degrees

–turn rightA(Default Angle) degrees

roll leftA(Default Angle) degrees

/roll rightA(Default Angle) degrees

^pitch upA(Default Angle) degrees

&pitch downA(Default Angle) degrees

|turn around 180 degrees

Jinsert point at this position

“multiply current length bydL(Length Scale)

!multiply current thickness bydT(Thickness Scale)

[start a branch(push turtle state)

]end a branch(pop turtle state)

A/B/C/D..placeholders, used to nest other symbols

Hello MORPHOCODE!

Is there a symbol to express the angle scale? It would be very useful. Thanks (:

Hi there,

no, in the current version there’s no symbol to control the angle scale. This is something we plan to add in the next releases.

Good day!

Help please, how to write and build with the help of Rabbit a three-dimensional bush-like structure

n=7, δ=22.5

ω : A

p1 : A → [&FL!A]/////’[&FL!A]///////’[&FL!A]

p2 : F → S ///// F

p3 : S → F L

p4 : L → [’’’∧∧{-f+f+f-|-f+f+f}]
