Yin Yang

Post by Shinji »

Hi, I'm new here but I also have some skills in Context Free from before.

I thought if there is a way to draw my favorite Yin Yang symbol, because I've not seen it in the gallery (maybe my fault :} ).

I have discovered one variant and I wanna know if there are some different variants of doing it :}

If you'll post some answers, I'll post the code :D

Here are two ways that come to mind:

Code: Select all

startshape yinyang

background {b -0.5}

rule yinyang {
	100 * {r -1.8} {
		CIRCLE {x 0.5}
		CIRCLE {x -0.5 b 1}
	}
	CIRCLE {x 0.5 s 0.25}
	CIRCLE {x -0.5 s 0.25 b 1}
}

path yinoryang {
	ARCTO {x -1 r 0.5}
	ARCTO {x 1 r 1 p cw}
	ARCTO {r 0.5 p cw}
	CLOSEPOLY{}
	FILL{}
}

rule yinyang2 {
	yinoryang{b 1}
	yinoryang{r 180}
	CIRCLE {x 0.5 s 0.25}
	CIRCLE {x -0.5 s 0.25 b 1}
}

Thanks John, I did it the same way as your first, through the rotation of two circles.

The second way is very interesting too, I've realized Context Free is on It's way since I used it last. I need to study new functions for sure :}

I wish a great New year for all of the Context Free crew :}

There is another way found by Seyen in 2007: the Taijitu.

Smart way too, hu?

It can be simplified like that:

Code: Select all

startshape Taijitu
background {b -.5}

rule Taijitu{
	360*{r .5}{
		CIRCLE{y -.5}
		CIRCLE{y -.5 s .2 b 1}
		CIRCLE{y .5 flip 90 b 1}
		CIRCLE{y .5 s .2}}
}

The same way, but thanks too.
