LSystem

Hi there,

this is a generic l-system library.
The mod will not really do something on it's own. It is thought to be used by other mods.

A l-systems is a thingy that can be used to generate structures that repeat variations of itself in itself. Those are often found in nature for example in trees. For more information about l-systems have a peek at the wikipedia article about L-systems.

Minetest already uses a simple l-system to generate trees l-system trees. That l-system seems to be thought for tree generation only (just a guess) so it is not very accessible and felxible.

LSystem aims at being flexible, expandable and jet complex and fast enough to generate structures at mapgen time.

How to use: Have a look a the github wiki for LSystem LSystem Wiki

Because this mod does not do stuff directly and I don*t want this to be a complete dry run, I have patched up a simple example on how to use LSystem to generate a simple and boring but vast structure.
(see LSystem Test in the downloads section)
! Do not use the example in a life world !
The example creates a plane field around you and than places the l-system's next generation on it, therby griefing everything that was there before.



As this is my first Lua project i'd be happy to hear about improvements to the sourcecode.

Nice idea. I will have to try it out. Would make worlds more interesting.

Great, thanks for considering.

Would this mod be able to spawn l-system trees as well?

With some modifications and a third dimension, the screenshot might almost depict a floor plan of a house. Intresting mod!

LSystem is thought to be quite flexible with it's l-systems. And you most certainly can build 3d structures with it.

Supplying an example that simulates the minetest tree l-system parser is an interesting idea. I'll look into that.

That might be very helpful. That way, I could spawn L-System moretree trees inside a normal voxelarea :-)
