pixel blog

The following is copied from an email addressed to Studio Kanzen, creators of SubPixel – a digital culture video blog.

Studio Kanzen,

this evening I discovered someone/something called “SubPixel”. My sister asked me what videos were mine on YouTube, saying that she did a search for “subpixel” and found something that looked like porn, so didn’t open it at work. Something about a guy with his shirt off and a girl with her hands somewhere near his groin. “No, I don’t think I have anything that looks like porn, or anything with a guy with his shirt off.”

What was she talking about? YouTube. Search.

I see… SubPixel: Clone a Willy Penis Mold Kit Review

Quite amusing, but no, not one of my videos.

Hi, I’m subpixel. I’ve been pushing pixels under that name since 2002 when I started taking club and party photos for Australia’s dance music community at InTheMix: “sub” as in music, and “pixel” as in pictures (digital photographs). On later reflection it occurred to me that the name had other interpretations, such as “subpixels” meaning “images from a subculture”, or “subpixel” being the thing (or person) underlying/behind the images I was capturing, especially since I was responsible for the images and rarely “in front of the camera” in my own photos, or those taken by other photographers in the Sydney scene.

After being an InTheMix photographer for a year or so, and having made many new friends along the way, I was more inclined to go where some of those friends were going, and less inclined to take on ITM photography assignments elsewhere, though still continued taking photos, including as “official photographer” for an underground party called Undercurrents, and today have an archive of some 70,000+ images and short video clips. I was without a camera – I mean a camera I cared to carry with me, since, now I think about it, I did actually have at least one other – for about 6 months two years ago, and found that to be a bit depressing. That slowed me down a bit, and I don’t seem to have been taking as many since then (or perhaps for a while before), though do go through spurts on occasion.

Photo madness in decline, I am still behind the pixels nonetheless. I acquired subpixels.com in 2003, and continued to use the name, especially for creative projects. In 2006, after a late night laptop-and-video-projector good times retrospective for a friend’s farewell at a city fringe music bunker (another friend’s house with a killer sound system and wall to wall wax) in Sydney, I was asked to supply visuals for a live electronic music gig called Laptopjam, and so the subpixel name moved on to be my VJ moniker.

I appeared mainly at live electronic gigs, VJ meetings and house parties in Sydney until I was roped in as resident VJ for a fledgling club night (Mind! Reggae Dubstep) in Brixton by Italian DJ Unity Selekta along with Earl Gateshead [Trojan Soundsystem] when I moved to London in 2008, strangely enough from my Gumtree listing looking for a place to live. Around the same time I discovered a local VJ community, VJlondon, where I made friends, had fun, and through which landed various gigs around London including a couple more live electronic gigs. I also joined the sizeable contingent of VJlondon crew appearing at LPM 2009 – Live Performers Meeting – in Rome, apparently the only Australian representative. Through Dr.Mo, who organised most of the VJlondon gatherings, I met architect and artist Alex Haw of atmos (currently working on the CLOUD for the 2012 London Olympics), with whom I collaborated to realise the Weather Projection installation at the inaugural Smart Light Sydney festival – me, a Sydneysider, scrambling to write the code in London (and in Rome after LPM!), and Alex, a Londoner, scrambling to put together the hardware (and content) in Sydney – such a mixed-up world we live in! Unfortunately I wasn’t able to make it to Sydney to see the result, but I’m back in Sydney now, and have rejoined forces with the live electronics party/promoter Midi In The City as well as taking up residency with the closely related TECHnique crew for their monthly techno parties and festival vibes at the Earthdance Sydney 2009 Campout. I have just completed another international collaboration, this time with Venetian producer and deepindub netlabel founder, Maurizio Miceli: a “VJ clip” for Way Out [DIDVJ002] to promote his latest EP.

On Thursday 18 December there was another VJlondon.org meeting at Cafe 1001, and again there was a triple-head setup with three projectors onto the back wall of the main room. Nice!

I’d decided that this time I’d work on this Processing sketch to have some 4:1 content for the massive screen. Up until this point, the tentacled object in space had been stationary and not especially interesting-looking. On Thursday morning I started tweaking the program with a view to actually being able to VJ with it, adding a bunch of new features like being able to move it around, make it bigger (“zoom”) or smaller, and more easily change some of the parameters. The tentacle shape changed a bit, as well as the appearance with some new oscillators to change the red, green and blue of the colour, and some mystery 1′s and 0′s on the surfaces. I’m no expert on lighting yet, but at least I managed to do something about it being so dark (as appears in Esfera mod by spxl 5).

I was perhaps a little too engrossed in what I was doing, and at some point realised I was already running late for the gathering!.. and rushed off to Brick Lane with my still warm code. The setup at Cafe 1001 was improved on last time, with a large table for laptops, etc bhind a raised bench with the projectors on it.

The tentacled space thingo was quite well received by the crew, though at that stage it was a bit of a beast to deal with effectively. Having pointer and keyboard inputs, I plugged in my Wacom and handed it to Rob to move it around while tapping at some controls myself on the keyboard. Even at 1920×480 it seemed to run pretty fast (and so it damnwell should!), and with the ultra-widescreen had a nice spacious and spacey feel about it.

I also tried running the radial gradient array sketch at that resolution, but, being a 2D pixel-based affair, my machine just wasn’t fast enough (or rather the program is too intensive) to get above a crawl instead of scintillating flashing colours.

Nevertheless, both sketches have been updated since then, and the Game of Life sketch created, and I’m starting to get a bit mental with trying to put nice comments and such on everything as well as make improvements and add new features. I think the commenting is taking as much time as anything else!.. and of course generally tidying things up, rearranging files on the webserver, updating all the past blog entries with Processing sketches to have a consistent look, and so on. I think I should really investigate creating a plugin or filter or something for WordPress – maybe a little database to keep track of the sketches and format them all nicely. I’m already running in to versioning issues, and changing the structure of the files is bad news for old blog posts!

Yesterday I did some work on creating a better timewarp effect – rather than change the speed of all of the oscillators, instead manipulate the “number of milliseconds” that have passed (this value is used in calculations by the oscillators) and also modify things like how far the object moves or rotates for the frame. Since the program was using simple easing logic, I’ve fudged it by multiplying the easing factor by the square of the (less then 1.0) timewarp factor, or leaving it alone if the timewarp factor is 1 or more (making the movement “faster than the mouse”, as it were,  seemed like a bad idea).

You see the brighter patch of red on the top-right of the sphere in the screenshot? That’s caused by five point lights just near the sphere arranged around the funnel of text. unfortunately the Java applet doesn’t seem to play on my machine (nor does version 5 of this sketch), and I think the lights (or use of lighting generally) is what causes it to fail. Then again, I don’t actually know, so this is only a guess! If you have the PDE installed you should be able to recreate the sketch from the source files.

For Thursday October 30, 2008.

The Dark Ages

It seems that I’ve been accursed with darkness the past few days. First the bulb in my lamp went, then this evening my ceiling light. Grr. Off to the shops for some groceries (and light bulbs) I go. I arrive home to find a flatmate cooking in the kitchen. A minute or two later..

*blink*

Power outage.

Not paid the bills?.. Wait, it’s not just us. Okay then. Good thing I’m planning to head over to Brick Lane just now for the vjlondon.org meetup. Hopefully the power will be reconnected by the time I get back. One can hear a lot of shouting and cursing in the local neighborhood. And cars blasting their horns. I’m sure that helped loads.

I put away shopping, pack my laptop, and head off. Walking down the road I note that this power outage is quite extensive. Even as I go further down Brick Lane, no lights. It’s not until Quaker Street that there seems to be any consistent power.

Coming out of the darkness and into the light

Listening to music on the way to Cafe 1001, the refrain from one track, “It’s just another excuse!”, seemed entirely appropriate for the situation. Come on London, what else can you throw at me? Darkness? Pah!

Emerging from the blackout zone and into happy lights and fun land, when I arrived at Cafe 1001 I found Dr.Mo and some others setting up, and a documentary film crew. And people practicing Capoeira. nebulus (nebulus design on Facebook, nebulus design videos on vimeo) had his custom hardware controller and had brought two projectors, added to a third and a Triple Head To Go made for a superwide 4:1 display across the back of the club. Nice! His realtime generative 3D visuals looked pretty amazing too.

I was asked to be interivewed by the film crew, which was for a University Video Project, and which is itself to be art of a 30 minute TV show. Not sure if I’ll be on TV. I’ll let you know if I am (or will be).

After the interview I asked to connect my laptop briefly to the triple-head in order to detect the screen size, and Mo suggested to set up properly instead of just testing it. After a small amount of confusion (thinking I should see more than one external display) I was beaming out on five heads (if you include my head and the laptop screen, though these latter two didn’t display the visuals output).

Of course none of my source material is in a 4:1 aspect ratio, so I had to look for footage that wouldn’t look too odd when stretched, and was also able to trim the top and bottom of some other clips on the fly for an acceptable result.

Actually, it was better than acceptable. It was starting to look pretty rad, if you don’t mind me reviving an old schoolyard term. I was well pleased with what I was seeing, and that, really is the point of doing this sort of thing in the first place.

I also liked seeing the custom visuals nebulus was pumping out. He had one laptop closed with another sitting on top of it, subsequently repeatedly overheating the lower machine, which was a shame. He managed to get things running on a single machine, though not quite as smoothly (and with, apparently, less complex visualisations).

Overall I had a pretty good night. When I arrived home the lights were back on (and flatmates were home).

Thanks to Dr.Mo for organising the meetup, nebulus and Silent Eclipse for the projectors, Deepvisual and whoever else supplied equipment.

A mini review from Deepvisual on the vjlondon forums:

Source: Next VJ meeting – Thursday – 30th of October – Café 1001

more fun…

very few of the regulars turned up???
instead we had a surprise visit from the lovely Joanne (Silent Eclipse) and an interplanetary freak-out from Nigel (nebulus) with his astonishing planetarium visualiser software.. George ( sub pixel) then took over the triple head for a while and put Neon through its paces.
the Student film crew were out in force, I found out I had started visuals before they were all born…
and we even had a walk-in VJ who had heard in the street that there were VJs in the venue this thurs and came along.

See a video of me playing on the triple-head below.

London VJ Meeting – 6th of August 2008 from vjdrmo on Vimeo.

Hmmm… of course I only appear in the clip tooling about in front of the camera hooked up for video feedback, trying to make something interesting happen. I’m not so sure it was working. ;o)

I don’t think I will make it to the 27 August VJlondon.org meeting tonight in Shoreditch, though, as I have a meeting about my upcoming gig at The Dogstar in Brixton at the same time. Maybe I can get back in time to catch the end. Now where did I leave that teleporter?

This post is for testing the pb-embedflash plugin for WordPress. Expect nothing to work, be surprised if it does. At the moment it seems that IE can display stuff and Firefox can’t… maybe a version problem. I’ve had issues with the Adobe Flash Player install, and there are possibly issues with Firefox 3.

From the What’s Cooking? department…

I’ve been to a couple of VJ events this week: the vjlondon.org meetup on Wednesday at T-Bar, and Immersion (a live experimental electronic music + visuals gig) on Thursday in The Flea Pit. I’ll mention that it’s great now living in Shoreditch, as both these venues are only a short walk away from my flat! :o)

Back to the story… it has occurred to me on more than one occasion that I will probably want (need?) to get into 3D at some point, and at these two events I saw some nice interactive 3D animation by pixelpusher (Evan Raskob), an earlier version of which can be seen in the video from the previous post (London VJ Meeting, Wed 9 July at T-Bar). I’m talking about the kinetic squiggles (which are input as gestures via his digital tablet) which zoom around. Evan had been working on this simple idea since last meetup, upgrading it from 2D only to 2D and 3D (combined), allowing multiple gestures to be loaded up as a set before “launching” (these are my own terms, I don’t know what Evan calls them!). I’ll have to clear some space on my Laptop (or get hold of another external drive – the one I brought with me from Sydney is out of reach at a friend’s house while they are at the Boom! festival in Portugal!) to upload the video I took at the event, and until then all I can say is that it looked quite amazing. That particular visual is produced in Processing from processing.org. I haven’t had much of a play with it just yet, but it looks promising! From the home page:

Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is an alternative to proprietary software tools in the same domain.

I’ve also had a word in my ear from Dr Mo about XNA the last couple of times we’ve met. I’d had the idea that I might use DirectX to build my own visuals engine at some point, and Mo’s feedback is that XNA is nice to work with, especially as the coding is done in C#.

I found myself installing the XNA Game Studio last night and discovered there is a free 3D modeling package: Truespace 7(.6) from Caligari. Upon further investigation I see that Caligari (or at least this product) is now owned by Microsoft, hence the plug from XNA. I remember the name “Caligari 4D”, and think it may have even been one of the packages available back in the day of the Amiga.

In any case, this eventually ends up in looking at videos of 3D animations, and this excellent example appears in Vimeo Staff’s Choice Picks:

Interstellar Sugar – Suryummy from Suryummy on Vimeo.

It reminds me of stuff done by the demoscene crew Farbrausch. If you like Suryummy’s video, you should check out the stuff that Farbrausch pump out in real-time!

Of course this video was created with software other than TrueSpace. Suryummy lists in a comment: maya, adobe*3, particular, live, reactor, absynth.

There is talk on the London Electronic Music Meetup (EMM) group about an Ableton Live DJ Workshop on a Saturday some time soon. I saw Live being used at Funckarma’s Dubstoned ep launch in London, but it wasn’t a “live” set, it was a DJ set, using Live. I want to know more… about using Live generally, but also because I know it has some sort of capability for triggering visuals. I have a project to work on with a DJ here in London, Unity Selekta, to produce visuals for his gigs, and I think I’m going to need some sort of sequencer. Live may be that sequencer.
