Developer’s Description

Simulate plant growth visually using Aristid Lindenmayer's mathematical model.

L-systems are formal string rewriting systems introduced in 1968 by the botanist Aristid Lindenmayer. To produce pictures from L-systems, we need some method of translating the strings into drawing instructions. A common alphabet is F = {F,+,-[.]}, interpretations take forms such as: + turn counterclockwise by a specified angle q; - turn clockwise by a specified angle q; F move forward one step while drawing a line; [ save position and angle; ] restore last position and angle. Features: you can use up to 5 rules. Select from a set of 15 examples to start with. The last set of instructions are saved, will be retrieved when the app is started or resumed. The maximum number of instruction is limited to 10,000,000 (10 Millions). Support of both portrait and landscape modes.
