A Little Friday Graffiti

The other day I sat in on an online dotBrighton talk on openFrameworks by James Alliban. One of the things he happened to mention in the hour or so long talk, was Graffiti Markup Language. Now this wasn’t the first I’d heard of the subject – I heard the term before in a session at some conference or other. On average, as my wife will attest to, I’d say I have to hear things 2 or 3 times before I start to listen. In any case, I took this recent exposure to the term as an excuse to actually do some googling and see what it’s all about. For anyone who doesn’t know, Graffiti Markup Language (or GML) is basically just a structured xml format used  “for archiving gestural graffiti motion data into a text file.” In a nutshell, gml contains a  whole slew of pt (‘point’) nodes and the amount of time it takes to get from one of those nodes to the next. Each point represents a x, y, z coordinate of an end stroke of a graffiti tag. So, just for kicks, I strolled over to this joint, downloaded 6 .gml files and started fooling around with […]

I know, I know. Recursive trees are a thing that have been done to death by – well – pretty much everyone. I just picked up a nice book on Processing the other day though and one of the first examples it gives is a nice recursive tree. In order to better understand the java/processing involved, I thought I’d take the time to convert it to a language I know. Actionscript, that is (in case you were wondering). After I got it ported and figured out what it was doing and why, I started thinking, that might look kinda cool in 3D. Then I remembered Seb Lee-Delisle had created a ridiculously simple to use 3d drawing api, so I put the two together and came up with the below (roll over to spin the tree around and click to generate a new one). If you’d like to have a play with it yourself, the code’s below (and of course you’ll need Seb’s stuff from the link above).
