Lighting Software

I've been working on a number of projects involving REAL lighing rigs - the sort of stuff you see on stage at gigs. It started out as an experiment, but more recently we've been working with some big fish in the lighting world... More details of that when I can talk about it! Here are some of the projects that I can release so far...

Eurolight - relighting tool

This software works with a Behringer Eurolight desk connected to your Mac via MIDI. Set up 12 basic lights, so they're dimmed by channels 1-12, point your web-cam at the stage, and hit "capture". That's it - you're done! Now you can preview all your lighting presets on screen, without needing the stage. There are a couple of limitations - it only tracks the faders, as thats the way Behringer implement their MIDI, so it can't recall programmed scenes. It also only supports 12 channels, even though this is supposed to be a 24 channel desk - Behringer don't support channels 13-24 via Midi (they have logged this as a bug, so maybe it can be fixed in newer versions of the desk).

This is an output image, showing a simlated lighting scene - the real lights were never in this configuration.

You can download this for Mac Leopard. You can try it out without a desk (not as much fun!) or lights using this test file

This work was published at SIGGRAPPH08 and Eurographics UK TPCG09.

DMX Monitor

The Eurolight app communicates with the desk via MIDI - mainly because MIDI is cheap and I had the parts for the system already. However in developing it further it became necessary to seperate the lighting sumulation from the desk, so I start using USB/DMX Interface. One of the first apps I wrote was a little DMXRecorder - just plug in the interfae, and it shows the values on each DMX channel.

DMX Surface

This app isn't going to make sense to a lot of people... I started dabbling with Logic, which lets you use MIDI devices to control your mix. However I don't have a suitable control surface, and anyway - my desk is pretty full, with a lighting controller. Mmmmm... the lighting controller has faders on it, I move the faders and the data goes into the computer...I write a little bridge... My DMX desk is now a Midi controller!!!

OK so it doesn't make any sense, cause you need a lighting desk, and a USB/DMX Interface, which probably cost WAY more than a MIDI control surface, but I already had the parts, so it didn't cost me anything, or take up any extra space in my already cramped office.

If you happen to have the parts to make use of this, then you can download it for Mac
