Modeling Plant Stems Using the Deterministic Lindenmayer System

Abstract

Plant morphology modeling can be done mathematically which includes roots, stems, leaves, to flower. Modeling of plant stems using the Lindenmayer System (L-system) method is a writing returns that are repeated to form a visualization of an object. Deterministic L-system method is carried out by predicting the possible shape of a plant stem using its iterative writing rules based on the original object photo. The purpose of this study is to find a model of the plant stem with Deterministic Lindenmayer System method which will later be divided into two dimensional space three. The research was conducted by identifying objects in the form of pine tree trunks measured by the angle, thickness, and length of the stem. Then a deterministic and parametric model is built with L-system components . The stage is continued by visualizing the model in two dimensions and three dimensions. The result of this research is a visualization of a plant stem model that is close to the original. Addition color, thickness of the stem, as well as the parametric writing is done to get the results resembles the original. The iteration is limited to less than 20 iterations so that the simulation runs optimal.

Ethnomathematics: Exploration of Mathematical Concepts in the Gate of Jamik Mosque Sumenep

“…If Euclid geometry discusses geometry in integer-dimensional spaces, such as dimension two and dimension three, then fractal geometry studies mathematics in fractional-dimensional spaces, such as 1/3, 2/3, and 5/2 (Widodo 2021). In other words, fractal space uses dimensions different from Euclid geometry, so fractal space is categorized as non-Euclid geometry (Juhari and Alghar 2021;Widodo 2021). Some characteristics of fractal shapes include self-similarity, repetition, and recursive (Barnsley 2014).…”

“…In addition, fractal shapes can also be found in nature, such as waves, mountains, clouds, plant branching, lightning, and others. Visually, fractals have high artistic and aesthetic value (Juhari & Alghar, 2021;Prusinkiewicz & Lindenmayer, 2012). On the other hand, learning about fractal geometry is still difficult for students to understand.…”

“…That is, the rules that are made are repetitive and return to the initial function. (Juhari & Alghar, 2021;Juniati & Budayasa, 2017).…”

“…In 3D space, the or symbol controls up or down rotation. The or symbol indicates left or right rotation in 3D space (Juhari & Alghar, 2021;Prusinkiewicz & Lindenmayer, 2012).…”

“…eir data shows that H. nepalensis harbors cancer chemo preventive and cytotoxic agents. In [13], authors have used L-System method for predicting the possible shape of a plant stem using its iterative writing rules based on the original object photo. In [14], authors mention that the applications involving 3D geometric models and generating images of objects are crucial operations.…”
