第八定理 | THEOREM 8
– Hector Rodriguez 羅海德
Theorem 8 is originally a 3-channel video projection installation exploring the intersection of art and mathematics. It is made using a specially authored software that decomposes every frame in a movie using a fixed database of frames extracted from another movie. The project is based on the mathematical concept of orthogonal decomposition, used in many surveillance applications. Theorem 8, however, redeploys this surveillance technique for very different purposes, to “read” one movie in relation to a second movie. This project thus visualizes the abstract mathematical concept of orthgonal decomposition. The idea is to select a fixed set of frames from one movie and then allow every frame in another movie to make a shadow projection onto each of those frames. Every frame in the second movie is decomposed onto those various changing shadows. By mixing the different shadow projections, it is possible to achieve an approximate reconstruction of the current frame in the first movie.
With this mathematical technique, it achieves a superimposition of frames from two different films: Godard’s Alphaville and Witch’s Cradle, directed by Maya Deren. The two films were selected because their filmmakers used light and shadow as dramatic elements. Godard can be seen a response to the rise of cybernetics and information technologies. Deren and Duchamp were interested in abstract mathematical spaces. The title, Theorem 8, refers to the orthogonal decomposition theorem, which concerns the idea of an object in a higher-dimensional space projecting shadows onto a lower dimensional space.
Since technique of orthogonal decomposition are often used in surveillance software, the work aims to foreground, deconstruct, and liberate the computational aspects of surveillance technologies. Its underlying philosophy is that radical politics demands radical artistic forms. It also shows how surveillance method can be subverted as means of reading or decoding the cinematic tradition.
Theorem 8 was orginally developed as a three-channel video installation, but it also exists in single-channel format, which can be screened with or without a short mathematical introduction, which is the version shown at WMC_e5.

About Hector RODRIGUEZ
Hector Rodriguez (WMC Research Director) is an experimental software artist whose work investigates the specific possibilities of information technologies to reconfigure our experience of moving images and our relation to film history. His work integrates video art with mathematics and computer science, exploring the tension between digital abstraction and cinematic representation. His work has been shown at the Saatchi Gallery (London, UK), the National Science Museum (Seoul, South Korea), the Museum Friedericianum (Kassel, Germany), Siggraph Asia (Singapore), and the WRO Media Art Biennial (Wroclaw, Poland), among other venues. He was a jury selection of the Japan Media Art Award. His digital experimental animation Res Extensa won him the Best Digital Work Award in the Hong Kong Art Biennale 2003. He received Hong Kong Contemporary Art Award’s Achievement Award 2012 with his computational installation system Gestus. His theoretical writings have appeared in Screen, Cinema Journal, Game Studies and various anthologies. He currently teaches computer arts, film theory, and art/science at the School of Creative Media of the City University of Hong Kong. His work Gestus-Beta was premiered at WMC_e4 (2010). He also conducted a 12-hour workshop series on interactive fiction using Inform 7 at WMC_e2, 2007, among other educational events at the various WMC exhibitions.
