light leaks

Created by Kyle McDonald and Jonas Jongejan for the CLICK Festival 2013 in Helsingør, Denmark, Light Leaks is a light installation comprised of fifty mirror balls projecting controlled light in the room.

The general idea was to make use of found objects, in this case mirror balls, which as Kyle explains to CAN have a fairly chaotic structure compared to the perfect grid of a projected image we are accustomed to. Having been influenced by Kyle’s work with Joanie Lemercier at ScreenLab in Manchester last year, where he learned how important peripheral vision can be in creating an immersive experience, Light Leaks is an attempt to fill a room with projected light in a way that can’t be achieved with projectors alone.

The pile of fifty balls sites in the centre of the room that has three projectors pointed at them. After placing everything approximately in their desired locations, it takes Kyle and Jonas about 15 minutes to take a series of five or six of structured light scans, consisting of 41 images each, where they photograph different patterns reflecting off the balls and hitting the walls. This collection of 200-250 images allows them to reconstruct the position of every pixel being projected by every projector. Once they have all that data, they line it up with a simple 3d model built in SketchUp which provides a reference for things like positions and normals of of the reflections.

Optically, this is much related to Kyle’s work with Elliot Woods earlier this year, ExR3. The main difference is this piece creates a dynamic scene using projectors instead of covering the room in markings.

Currently the piece consists of a handful of scenes that last about twenty seconds each. Kyle explains that it is really difficult to develop this kind of work without all the materials in place, and they are looking forward to the next opportunity to install this and push the visuals farther (now that they have all the technical challenges solved).

Kyle guided the overall design and wrote the code for recovering the position of all the reflections, and Jonas focused on the shader code that implemented some of the different effects that fill the room.

A scattered array of mirror balls reflect light from multiple projectors, filling a room completely with small reflections, casting patterns that fill the visitor’s peripheral vision. Creating a curious space that alternates between a meditative state, and an uneasy imbalance. An experiment in combining a found object with computer vision in order to create a profound and unusual experience.

Creating a satisfying connection between found objects and hi-tech wizardry, artists Kyle McDonald and Jonas Jongejan were one of the many highlights of Denmark’s Click festival earlier this year. It’s been a long time since disco balls were cutting edge technology, but the duo have managed to give them a new lease of life with Light Leaks.
Assembling fifty disco balls of assorted sizes in the centre of a room, they subjected them to three fixed-point projectors in turn, precisely mapping the refraction points thrown up by the various combinations of reflected light. By feeding this into specially written software that 3D maps the space, it’s possible to create carefully formed projects out of the scattered snowstorm of patterns.

“The concept of controlling every reflection of a mirror ball seems absurd at first”, McDonald tells LiP, “but when you use technology creatively you can reduce the real world to something symbolic and malleable. This installation pursues a perspective of physical, analog space as something addressable, or even digital”.

The effect is certainly visually baffling, forcing the viewer to really work at processing what they’re seeing. It forces you to reassess your understanding of analogue objects, with these almost comical, kitsch objects becoming part of a complex system. “I’m not trying to draw on disco references, or the 70s, or anything culturally related to mirror balls. In the space itself, you lose track of the fact that they’re disco balls, and they become an accessory to the installation” says McDonald. The effect is that these familiar objects begin behaving in unfamiliar ways, more like preprogrammed LEDs than mute, reflective surfaces.

The technology behind the installation is deceptively simple however – three projectors, a camera for calibration, and open source software custom built on a standard computer. The room may look as if it’s full of dancing lasers, but it in fact only uses simple principles of reflection and refraction. “I was looking for a creative way of filling a space completely with projected light, allowing control over the entire field of vision of the visitor” explains McDonald, and with Light Leaks Jongejan and McDonald have certainly achieved this.

Deze bijzondere kunstinstallatie van de Deense kunstenaars en whizzkids Kyle McDonald en Jonas Jongejan bestaat uit een donkere kamer, 50 in grootte variërende discoballen en een stel beamers, waarmee dankzij vernuftige software allerhande patronen op de wanden kunnen worden weergegeven. Hypnotiserend!

Una matriz dispersa de cincuenta bolas de espejos reflejan la luz de tres proyectores, llenando una habitación completamente con pequeñas reflexiones, proyectando patrones que llenan la visión periférica del visitante. Crear un espacio curioso que alterna entre un estado meditativo, y un desequilibrio incómodo. Un experimento en la combinación de un objeto encontrado con la visión por ordenador para crear una experiencia profunda e inusual.

「ミラーボールが50個も並んでる部屋」と聞くと、いかにも落ち着かなそうな響きがします。でも、デンマークのメディア芸術祭「CLICK」で公開された作品を見ると、我が家にも何個かミラーボールを置いてもいいんじゃないか…という気がしてくるから不思議です。

カイル・マクドナルド（Kyle McDonald）さんとジョナス・ジョンゲジャン（Jonas Jongejan）さんによる作品「Light Leaks」は、ミラーボールに降り注ぐ光をコントロールするプロジェクターを使ったインスタレーション。

この作品は、部屋の構造を立体的にスキャンして、壁や天井に反射する光の模様をマッピングしています。立体スキャンによってミラーボールの光がそれぞれどの場所に投影されるのか予測し、SketchUpを使って室内の光反射をモデリングしているのです。

Creative Applicationによると、この制作チームは今後、より詳細な構造データの取得、コントロール精度の向上を視野に入れているそう。ミラーボールの反射光をドット単位で制御するプラネタリウムとか欲しいです！

见到镜面球形灯，我们总会联想到俗气的舞厅，现在我们终于可以想到点别的了。将迪斯科球灯从蹩脚的意象中解救出来的是Kyle McDonald、Jonas Jongejan和他们近来于丹麦CLICK艺术节上展出的装置作品Light Leaks。

Creative Application Network报导了这件作品是如何“试图用一种投影机本身无法做到的方式将投影灯光填满房间”。作品由五十个镜面球形灯组成，图像被三个投影机映射到球形灯上。这使黑暗的房间被波浪般的像素化灯光淹没，为观众带来身临其境的体验，既适用于俱乐部，也适用于你坐下小憩的客厅。

以下是两位艺术家对该项目的描述：

散乱排列的镜面球形灯反射多部投影机的灯光，使房间完全被小型反射光填满、访客的周边视觉充满变幻的形状。创造一个时而静默冥想、时而失衡不安的空间，引人好奇。它是一个将既有物体和计算机视觉结合的实验，创造深刻而别样的体验。

所以，如果你觉得迪斯科球灯早过时了，你就错了，他们依然鲜活地存在，并作为一种新型的画布被复杂的投影映射灯光赋予新生。
