Luz Studio – [VIDEO] Game Physics Update

July 31, 2011

Luz is an open-source live motion graphics editor and performer.

And game design studio.

Levels are created as standard Inkscape SVG files:

Properties of the objects are parsed from the “Description” field, as seen with “elasticity” in the above screenshot.

Watch on YouTube

Animated Luz actors can be placed around a level, such as the background and the flag pole in the above video.

The next step is to add triggers and conditions for winning/losing, and this will make a solid puzzle game development platform.

Luz Studio – [video] The Moon! live with Saffire Bouchelion

July 8, 2011

What a pleasure and an honor to create with Saffire Bouchelion!

That was a lot of fun!

We used Luz to create the projection with live improved Wacom tablet and spectrum analysis input.


Luz gets DMX lighting control

February 12, 2011

DMX is a standard for controlling lighting and other show devices (lasers, smoke, fog, heat machines). Many of the club and venue lighting systems are DMX, especially the larger ones.

Luz can now output DMX commands via an Enttec DMX USB Pro, a serial-usb device that is plug-n-play in Linux.

Luz meshes VERY well with DMX!

Conceptually, DMX is a 512-channel data bus, each holding a 0-100% activation (0-255). Each lighting fixture is configured to listen to a subset of those channels (often 3 for RGB). That’s it.

Luz Variables form an unlimited-channel data bus, each holding a 0-100% activation:

Luz Variables get their values from human inputs, or from animations over time or beats.

Luz as a live DMX lighting controller feels very natural.

What does DMX control get us?

Luz can now make the house lights dance. It can animate color and brightness changes on the beat of the music, or via human input on any sort of input device (Wacom Tablet, Wiimote, MIDI piano), or via the Spectrum Analyzer, or any other application that can send OpenSoundControl to Luz on a LAN or Wifi network.

You could control a stadium’s lighting with a Wiimote. You could play the club lights with a midi piano.

Below is a video of some early experimentation with projector-lights synchronicity. I directly connected the Spectrum Analyzer’s signals to color control of the primary actor on the projector, and also to the RGB color of four Colorsplash JRs LED DMX lights:

Right now I’m at the point where all the technology works, and I’m deciding how best to integrate DMX into the Luz Studio experience.

I’m thinking that DMX plugins will be in your Directors. So each of your Directors will have a handful of Luz Actors creating the projector image, and a handful of DMX plugins controlling the house lights.

This makes it easy for users to create full projector + lighting packaged experiences, and even to crossfade between lighting experiences in sync with the visuals on the projector transitioning gradually between Directors (using Director Cycle or Director Voyage).

I’m open to your thoughts, ideas, questions, proposals for collaboration (Portland, OR).

Luz is very easy to install on Ubuntu. See the easy Luz installation instructions on the project page.

Luz Studio is free and open source software. My favorite toy and my gift to you! If you like Luz and would like to donate a small amount or become a $1/month Luz Project Supporter that would also be most appreciated!


Luz Studio 720p LightTroupe Rendering

February 4, 2011

This video was produced while testing the Luz Studio video production workflow. It has some great moments so I thought I’d share it.

There’s a video tutorial on how to produce HD video with Luz on the Luz tutorials page.

Luz at Play

August 26, 2008

Creations like this happen pretty much nightly in my house these days.

This is a visual synth created in Luz.

I’ll start recording these directly on the computer if I ever figure out how to make RecordMyDesktop capture the playing music instead of the mic.   Ugh!
