Jitter newbie – generating shapes within certain parameters?

August 14, 2014 | 7:44 am

Hi all – long time lurker, first time poster.. hah!

I’m just starting out with a new Jitter project/learning exercise and was wondering if someone might be able to point me in the right direction. One of the things that I’d like to have Jitter do is generate shapes within certain parameters – so, for example, something like a simple child’s drawing of a maple leaf but with each iteration having slight differences etc. Is there any particularly efficient way of doing this that I might otherwise manage to ignore? (Such as with custom shaders or something – I admit my knowledge of this area is practically non-existent, so this is probably a ridiculous idea!)

But, yes, thank you in advance for any ideas that you guys might have – in the meantime I’ll get back in to pouring over the tutorials!

I think you would be interested by the Iterated Function System and L-System example patches in the Gen folder.

Basic example http://www.nzeldes.com/Fractals/Fractals_core.htm

After that I would dig around through the Jitter tutorials by Peter Elsea

Thanks Ehdyn, these are really great! :-) I’ve had a scan over Peter Elsea’s tutorials and will have a really good look, seems like there’s a lot of relevant stuff there.

I think what I really want to achieve is to create multiple, individual instances of – say – ‘flat’ (although that is not necessary) leaf shaped polygons that are produced by certain inputs. Is there maybe some combination of jit.gl.sketch and jit.gl.multiple that might be a good approach? Perhaps it would be easier to not have the shapes be random/semi-random. (I mean something like the visuals around 0:50 in this video from the ‘Trinity’ project http://vimeo.com/64894353 – so the ‘performers’ actions will trigger/throw shapes and so on…)

But – yes – sorry for rambling on again, haha! I maybe need to reassess what it is I’m trying to achieve… but I suppose it’s a good to write it out even just as a sounding board sort of thing!
