turtle.lua - Drawing library

[arthure]

Minimalist turtle graphics implementation in lua.

Source code : https://github.com/arthurealike/turtle.lua



If you are familiar with turtle graphics, it will be super easy to use our tool with chain methods.
Create a turtle instance, give commands it on load() or when an event is published, then call its draw function in love.draw(), and it is done.

Code: Select all

require "turtle"
local triangle = Turtle()
function love.load()
	local red = {1, 0, 0}	
	triangle:setcolor(red):left(60):forward(50):right(120):forward(50):left(60):backward(50)
end

function love.draw()
	triangle:draw()
end

You can also create multiple instances.
There are many methods that we described in readme on repository. We added also animation state that you can toggle drawing state such as stop and play in real-time. We'll keep updating/developing, finding better approaches to achieve turtle graphic's all methods. Thanks for supporting. Keep in touch!

I'm not old enough to have experienced it, but I'm old enough to know about it. This is a fun library!

Let me tell you a secret, I did not experienced turtle graphics too But it is real fun and can be used in different ways. Thank you!

I'm ancient enough to have had the pleasure of doing turtle graphics decades ago, and it isn't less fun now than it was then.
It's a neat thing what one can draw with this; L-systems, patterns found in nature, fractals, chaos... the possibilities are endless!

I was trying to implement a fractal engine for love2d, then i found myself as writing turtle in lua. As you said, turtle is a super easy way of implementing fractals.

It is updated with new methods.

Huh... I've never even heard of turtle graphics!
Does it have any relation to Fourier Series, or is it entirely different?

Procedural graphics creation has always been a fascinating subject to me.

It is different; just a way to graph things... that said, it is indeed powerful. One could implement things like fourier series based waveform drawing, rule-based auromata visualization, L(indenmayer)-system based drawing (more natural things e.g. trees, leaves, etc.)

It has more to do with these: http://cyberneticzoo.com/cyberneticanim ... -american/

Logo is a language with which you can give commands to a "turtle" (most commonly an arrow painted on the screen, but there were robot models that painted on paper too, as shown in the link). Basically, commands are relative to the turtle: forward N, right N, pendown, penup, etc. "Turtle graphics" refers to a way of drawing graphics using that basic concept from Logo, without being a Logo language implementation itself.

I keep developing and try to make it well documented guys, thanks for your interest.
