L-Systems Explorer

[Guest amgsoft]

Description

L-systems are formal string rewriting systems introduced in 1968 by the botanist Aristid Lindenmayer to model the growth of plants.

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:

1 You can use up to 5 rules.

2 Select from a set of 15 examples to start with.

3 The last set of instructions are saved, will be retrieved when the app is started or resumed.

4 The maximum number of instruction is limited to 10,000,000 (10 Millions).

5 Support of both portrait and landscape modes.
