The Lindenmayer System, often called an L-System, is a mathematical model used to describe the growth patterns of plants. It uses a set of rules to create strings of symbols that represent the structure of a plant. By applying these rules repeatedly, complex shapes and patterns can emerge, mimicking the natural growth of trees, flowers, and other organisms. Originally developed by biologist Aristid Lindenmayer in 1968, L-Systems have applications beyond botany. They are widely used in computer graphics to generate realistic models of plants and landscapes. This makes them valuable in fields like animation, game design, and even fractal art.
