8 Data Visualisation Links

Sunday, June 20th, 2010

For an assignment recently I had to do some research into computational arts practices and information design practices in the context of data visualisation. As such I did some hunting around for different practitioners, examples and related websites and I’ve put together this small list of websites. I did have a number of others but I’m not quite sure where they went – must have closed the tabs by accident:

The New Design

Thursday, February 12th, 2009

You may have noticed things in the design gradually changing around here over the past couple of weeks.

The design itself is now finished. Unfortunately though, since I’ve widened the main content section a fair bit, it’s put some of the individual posts out, such as images behind code sections. Actually, mainly images behind code sections. I’ve gone through and cleaned up all of the ones I’ve found so far. If you happen across any that are still out, it would be greatly appreciated if you could leave a comment on the post to let me know.

Something new I have incorporated with this theme is my Twitter stream, running down the bottom right of the page. I’ve had it running on my other blog, Still as Life, for a while now, figured it’s about time to put it it on here too. My tweets are more web design oriented than computational arts, and even more so just what I’m up to in general. So when I am working on something, I’ll usually be tweeting about it, be it web design, computational arts or something else. Follow me if you are on Twitter and want to keep up to date on what I’m doing and my latest projects.

The background image I have used is a still from the output of one of my recent Quartz Composer audio visualisations. I’ll be putting it up here when I get a chance, along with a couple of variations on it.

Have a great one!

Happy New Year Everyone

Thursday, January 1st, 2009

Happy new year to everyone out there! Best wishes to you all and a prosperous 2009 for everyone!

I’ve been pretty quiet on here the past few months unfortunately as I have been pretty busy, though if you follow me on Twitter, I am relatively alive. Hopefully you’ll be seeing a few more blog posts from me soon as I’ve got a number of things on the go, and a few things finished that just need to be written up.

I’ve been playing with Quartz Composer a fair bit and have a few new audio visualisers for you coming fairly soon, along with a new design for this blog based on one of these visualisations, so keep an eye out for it soon! The graphic design is almost finished, so hopefully I’ll get it all done up and live in the next week or two.

For a bit of a look at what I’ve been up to for Christmas and new years, have a look at my other blog, Still As Life and leave your comments about what you’ve been doing too.

Have a fun and safe holiday everyone, and enjoy 2009!

Fractalesque

Thursday, November 6th, 2008

Done with Quartz Composer with the intention of replicating the appearance of a Fractal Flame rendered through Scott Draves’ Flam3, except live rendered based on audio input.

This isn’t a fractal, but I think it does re-create the appearance quite well.

The video quality isn’t even close to the live render quality, but it gives you a good idea of it.

The screen recording here has taken the mic input and used it for the animation. The song used in this recording is “August (Reggae Rework)” by el-B from http://ccmixter.org/files/elB/16075 under a Creative Commons Attribution Noncommercial 3.0 License.

You can download the Quartz file here, note though that while this will open in Tiger, it will not render correctly, OS X 10.5 Leopard is required for it to run correctly.

It should also be noted that the video above was rendered on a Macbook Pro with an Intel Core 2 Duo 2.4ghz with 2gb of RAM and an 8600m GT and it averages 5 frames per second, so to really experience the full potential of this, it needs to run on a Mac with a fairly powerful video card like a Mac Pro, the iMac’s and new Macbook Pro’s should also render it quite nicely.

The reason it is so intensive is because there are a number of iterator and replicate in space patches along with LFO’s and interpolator’s that are affected by both the audio volume peak and the audio spectrum, so depending on the volume and the type of music, the visualisation develops more variation.

Plasma Box – Quartz Composer

Tuesday, November 4th, 2008

Plasma Box - Quartz ComposerThis is a fairly simple Quartz Composer visualisation that I developed to be a screensaver or to run in the background of an environment to help develop an atmosphere. The idea originally came from when I was walking past the Chalk Hotel in Woolloongabba in winter and noticed that they had big LCD’s on a couple of walls playing a video loop of a fire to help create the sense of warmth and a warm atmosphere, even though there was almost no heat actually being produced by the LCD’s.

What I have created here is floating plasma that slowly floats from the bottom to the top of the screen and accumulates at the top. Audio input is taken from the microphone and combined with an LFO so that it is constantly varying between the base colours that the LFO covers and then other colours dependent on audio spikes. The audio input is also used to make the plasma “shy”, that is, as the input volume increases, the plasma starts to get smaller and disappear until the volume starts to subside again, then it comes back.

The basis of this is created with a Quartz Flame Image patch, ideally, I would have liked to redo this with a more controllable particle system, but that is for another time.

Download the Quartz Composer file here. Note that this requires OS X 10.5 Leopard. It will not work in Tiger as I have used patches that were not available in Tiger.

Check out the video below which shows the visualisation running with the song “Wired but Disconnected” by duckett.
