VPT 5.1 available

After nearly 2500 downloads of the first version of Video Proejction Tools VPT 5 released in december 2010, I am happy to announce the new version 5.1, partly based on feedback from workshops and the VPT forum.

The release focuses on all the possibilities to expand and customize VPT to be the right tool for your particular project.

This includes a vastly improved controller section, making it possible to control almost every feature of VPT from another application (like maxmsp, processing and PD), computer, sensors through the arduino microcontroller, midicontroller as well as built in lfo controllers for automating control and software sliders and buttons. This comes on top of the already existing built-in preset and cuelist system for playback. Through OSC, VPT parameters can relatively easy be controlled by gestures, using camera or kinect tracking.
You can easily set up VPT to control simple projector shutters by controlling servomotors using the arduino module.

Templates are provided with the download for exploring OSC on maxmsp and Processing, PD will follow later. Arduino templates for input/output as well as a servo example is also included with the download.

VPT can be used with multiple projectors using Matrox Triplehead2go, and the latest version also includes support for multichannel sound: The movie sources can be individually routed to up to eight channels, depending on your sound card. Using the provided maxmsp template it is possible to process the sound further.

VPT 5.1 includes a new possibillity of processing the sources using the FX bus. The FX bus consists of eight FX chains, modules which contains shader based effects. New FX chain modules can easily be made using the provided maxmsp/jitter template, and can be dragndropped onto the existing FX chain to replace it, making it easy to customize the effects to your particular need.

Three new sources have been added to VPT: A solid (if you just want a colour in a layer), a noise texture generator and a text module which can either use text from file, osc or typed text. A maxmsp/jitter template is also provided if you want to create your own source.

VPT is a free multipurpose realtime projection sofware tool for Mac and Windows developed by HC Gilje. Among other things it can be used for projecting video on complex forms, adapt a projection to a particular space/surface, combine recorded and live footage, or for multiscreen HD playback.

snitt

On November 13th my second solo exhibition at Galleri 21 in Malmö opened, and it runs until December 5th.

I created two site-specific installations, which both derive from recent work, investigating the relation between light/projection/shadow,space and movement.

At the moment I only have decent documentation of one of the works, so I will just briefly mention “Kaos på dej”, which is basically a variation of the blink (light/shadow) installation but with some furniture.

Snitt, which spanned over three rooms in the gallery, is a projection of a white line onto the surfaces of the gallery: “A straight line moves slowly through the three rooms of the gallery space, cutting the space into different sections (snitt). The movement of the line, “attacking” the space from different angles, focus the attention of the viewer on the physical qualities of the space.

The physical properties of the galllery space (the walls, ceiling,floor, door openings, light fixtures etc) modulates/breaks up the straight line into a continuously evolving pattern of line fragments, depending on the position of the viewer and the angle of the line in relation to the architecture.”

The view in the inner room:

And here is a video showing some of possible configurations of line-space.

U trust blink?

I spent last week in Dortmund, preparing for the Trust exhibition, showing at the new Dortmund U. Trust is an exhibition curated by Andreas Broeckmann and Stefan Riekeles as one of the exhibitions for ISEA2010 which takes place in the Ruhr area later in August.

Dortmund U used to be the Union Brauerei (brewery), and is now turning into a center for different cultural activities.

I am showing a new version of blink, with new sound and a few visual changes as well.

Other participating artists in the exhibition:

Seiko Mikami (jp), Carsten Nicolai (de), knowbotic research (ch/at/de), Milica Tomić (rs), Ariel Guzik (mx), Joan Leandre (es), Joyce Hinterding (au), Julien Maire (de/fr), Naeem Mohaiemen (bd), Sophie Bélair Clément (qc/ca), Konrad Becker (at), Verena Friedrich (de), Antoine Schmitt (fr).

I am happy to be part of this group of interesting artists, and look forward to the catalogue which will be ready for the ISEA conference.

The exhibition is on until September 5th.

Wind-up birds sound recordings

As mentioned in a previous post, Wind-up Birds made an appearance in the foresty hillside of Fløien. Fløiensvingene (The Fløien turns) is a curly path up the steep hill (as steep as 25 degrees), starting at about 180 m above sea level, and ending at about 300m.
It is a city forest, blending the sounds of the city with sounds of nature, as well as the sound of all the people using it.
I quickly edited together a few sound recordings from various points along the path to give you an impression of how the wind-up birds blended into their environment.

They´re back

For the occasion of Festpillene i Bergen 2010, a flock of Wind-up Birds has taken over the mountain side of the Fløien mountain. More specifically along the windy, steep path through the spring-green forest called Fløiensvingene. They will probably stay a few weeks. This has created a lot of buzz among the people using the path, so I will try to spend as much time as possible there to listen to audience reactions.

They might sound similar to previous generations, but there has been a few changes under the hood: The wood blocks have this time been milled instead of glued, making them more robust. Thanks to Ivar Bergseth and his CNC mill!

I use a new set of xbee modules, the xbee 2.4 pro digimesh modules. This gives a more stable network and is much easier to work with than the previous firmware.

I made new more practical circuitboards, which I got manufactured at BatchPCB, making the job of assembling the woody boards much easier. This was my first attempt at working with Eagle PCB circuit design software, but I leaned heavily on Roar Sletteland´s previous PCB layout for the first generation.

blink at Sonic Acts XIII in Amsterdam

I am presenting blink at the Sonic Acts festival in Amsterdam. The installation is part of an exhibition that will be on until May 2nd at NIMK.

I have added some images of this version of the installation in my blink flickr set.

The theme of this year´s festival is The Poetics of Space, and the program is packed with audiovisual performances, screenings, a very extensive conference program as well as the exhibition. There is also an accompanying book, which contains the text that Mitchell Whitelaw wrote about my work.

I will be giving a presentation on the last day of the conference.

The program for Sonic Acts is avaible online, but also you can download the programme booklet as PDF.

Esemplasticism: The Truth is a Compromise

blink v2, originally uploaded by hc gilje.

Blink is part of an exhibition curated by Hicham Khalidi, produced by Den Haag art space TAG, made for Club Transmediale that opens in Berlin today.

From the exhibition decription:
Our brains are esemplastic. They are perfectly evolved for pattern recognition, designed to shape disconnected elements, like the incomplete or ambiguous information we get from our senses, into the seamless whole of our experience. What we see, hear, touch and feel is folded into an amalgam of data, emotions and cultural baggage. And in the contemporary world, this esemplastic power is pushed to the limit in the sea of information that we are floating in: data-visualizations, scientific studies and computer analyses become increasingly abstract and disconnected from our normal experiences. Are we losing our sense of meaning as we fail to join the billions of dots? What compromises are we making when we try to settle on a particular interpretation?

The works in Esemplasticism – the truth is a compromise are mostly low-tech, using everyday objects and media. Employing sound, objects and synchronicity; relatively ‘old’ technologies like field recordings, music, video, and projection, each piece lifts the curtain on the perceptual tactics that our esemplastic/apophonic/pattern recognising brains employ to negotiate the world; with wit and irony, they have much to say about verisimilitude as each exposes a different fracture between our expectations, our perceptions and our compromises about the objective ‘truth’ that exists ‘out there’.

Participating artists
Artists: Edwin Deen, Daniël Dennis de Wit, Lucinda Dayhew, Anke Eckardt, HC Gilje, Terrence Haggerty, Yolande Harris, Alexis O’hara, Pascal Petzinger, Mike Rijnierse, Willem Marijs, Bram Vreven, Katarina Zdjelar, Valentin Heun, Sagarika Sundaram, Gijs Burgmeijer.

I will post links to the catalogue when that becomes available.

The exhibition will be on until the end of February.

For me this was an opportunity to improve the installation both esthetically and technically. I constructed a platform for the equipment using a laser cutter, which turned out quite nice. This greatly simplified the installation of the work. As mentioned in previous posts, the installation uses my dimsun lighting system, and the design for this will be made available shortly.

Due to other obligations I needed to set up my installation before everyone else. It was a strange experience to work alone in the 900m2 empty building in Spandauer Strasse, close to Alexanderplatz. My only companion was the stepladder which also became the model for my documentation.
