\"\"As mentioned<\/a>, I spoke at 404 at the Royal Hospital Kilmainham on Saturday, October 7th.<\/p>\n

I was demoing a little Swift Playground<\/a> I had thrown together just after WWDC, when ARKit was announced.<\/a><\/p>\n

 <\/p>\n

The original demo, a flat little SpriteKit-based playground, was not terribly exciting, so I spent a bit of time throwing together a few passes at more engaging content (because, frankly, I was a little panicked this was going to be the most boring demo ever).<\/p>\n

The obvious choice was to make a SceneKit-based playground, with 3D objects. But, after a couple hours in Blender, the realization dawned that I’m not quite a 3D artist just yet.<\/p>\n

With my 3D efforts the demo wasn’t much better than the 2D version. So I switched tack. Apple provides some excellent sample code for most of their frameworks, including SceneKit. So I borrowed the supercool fox named Max from the\u00a0Fox2 SceneKit sample code from Apple<\/a>\u00a0and dropped him and his friends into the scene, animations and all. Waaaay better.<\/p>\n

I found I couldn’t stop there, and wound up using the light sensing capabilities of ARKit to make an homage to my first apartment in Brooklyn — turn the lights on bright and you could see a horde of bugs appear, turn them down and they magically disappear. If I just introduced my roommates bringing home a cat and making them all disappear, even in the light it’d be a near perfect simulation. Due to the setting, I couldn’t control the lights, so the Brooklyn Apartment playground was out of bounds, but I presented the other two to a crowd of varying size on the day.<\/p>\n

The gang who ran 404 did an excellent job with the event; there were loads of interesting speakers and installations. I’ve posted the html version of my slides<\/a> from the day and a PDF of the presentation with notes<\/a> (it makes for more interesting reading than the slides on their own, lucky you).<\/p>\n

You can get the source code for all these playgrounds from my Github repo<\/a>, and for your indulgence thus far, here’s a video of the fox in action:<\/p>\n
